How to know which bond is the strongest among those molecules who have the same bond order?
Q. As N2 forms triple bond and F2 forms single. So we know that bond in N2 is more stronger. But how can we tell which has the strongest bond among F2 , Cl2 and Br2 ?

How do you work out bond energy changes?
Q. In a chemical reaction, how do you work out the energy change? Is it: Energy of Bonds made - Energy of Bonds broken or Energy of Bonds broken - Energy of Bond made? If the answer is negative, is the reaction endothermic?
Asked by - - Tue Apr 28 13:28:01 2009 - - 1 Answers - 0 Comments

A. Firstly, if it is negative it is exothermic as the negative sign shows that the heat is on the products side of the equation, so it is given out, rather than taken in. And it is Bonds Made - Bonds Broken. So for example, if we look at the nucleophilic substitution of Br - Br, into CH4. The products will be CH3Br and HBR. So add up the Bond Enthalpy of the new bonds, which you will have to trust me equals 1889 kJ per mol. (The values are in your data booklet.) Then add up the Bond Enthalpy of the old bonds, which, again you'll have to trust me, is 1850 kJ per mol. So Bond Energy Change is 1889 - 1850 = 39 kJ per mol. So for this example, the reaction is endothermic. Hope that helps.

How is bond yield calculated when interest payments are not reinvested?
Q. The most common number used to compare different bonds is yield to maturity (YTM). However, YTM assumes interest payments will be reinvested at the coupon rate (which is unlikely since interest rates can fluctuate anytime). So how does one calculate yield or rate of return on a bond in the case where interest payments are not reinvested at all? Thanks. The nominal yield seems like the right answer. Can that the expand though to include capital gains/losses incurred from buying the bond at a discount/premium? Thanks.

What is the difference between and ionic bond and metallic bond?
Q. We are studying chemical bonds and reactions in class and I really don't get it. Can you help me? oh and what are some similarities between ionic and metallic bonds. . and which is stronger: a single, double or triple covalent bond? uuhm..so far I got stupid answers. Please help.
Asked by ARE YOU CRAZY?! - Sun Dec 6 15:40:37 2009 - - 3 Answers - 0 Comments

A. Wow, these people are giving the worst answers. So I don't fully understand how metallic bonds work, but they're similar in that the bonded atoms don't share any electrons. In an ionic bond, some of the electrons from one atom movie into the outermost shell of the other atom, so the charges become opposite but equal. For example in NaCl, an electron from the sodium goes moves into the chlorine, making the Na+ and Cl-. Because the charges are opposite, the atoms are attracted to each other. And for the covalent bond question, the more bonds there are, the stronger it is.

What will happen to my bond after the company gets bought by a private firm?
Q. I have in mind the 20-year bond issued by Clear Channel Communications. The company got bought by a private company and since then the price of the bond has been going down (about 20 percent over the past six months.) Its ratings are still the same BBB. What will happen to this bond? Any suggestions on what I should do? Thanks a lot.
Asked by Dan - Thu Mar 13 22:46:42 2008 - - 1 Answers - 0 Comments

A. I'm not familiar with the sale, but normally, nothing happens to the bond other than a fluctuation in market value. The buyer assumes all liabilities of the bought company. If the buyer company has a better or worse credit rating than the bought company, the market value of the bond will go up or down, but the face value / redemption value won't change.

Asked by Ferasha - Sun Jan 18 16:58:14 2009 - - 1 Answers - 0 Comments

A. A covalent bond is a very strong bond where the atoms are physically sharing the electrons within the bond. Covalent bonds generally take place between two non-metals (to the right of the "staircase" on the periodic table) A hydrogen bond happens because of the polar nature of the covalent bond that hydrogen makes with oxygen, nitrogen, or fluorine. Since these atoms are highly electronegative (basically, they hog the electrons that they are sharing), they take on a partial negative charge (from the extra electron density). At the same time, the hydrogen that they are bound to takes on a partial positive charge. These partial charges are what form the hydrogen bond.

A. First of all BONDING and grounding are not the same thing! Do not connect the bond wire to the grounding conductor! I assume you are referring to a hydromassage bathtub, and not a hot tub. The term hydromassage bathtub is how the National Electrical Code refers to a tub mouted inside with a water supply and a drain, as apposed to a self contained unit which is referred to as a hot tub. However, if you ARE referring to a hot tub, the principle for bonding is the same. According to the National Electrical Code 2008, "All metal piping systems and all grounded metal parts in contact with the circulating water" of the tub are required to be bonded together. If the water supply lines are copper, they must be bonded, and for that you will… [cont.]

What exactly is the correlation between electronegativity, bond strength, and stability?
Q. I read in my textbook that the electrons in a C-H bond in a carbohydrate, for example, are less tightly held and have more energy than double bonded Carbon and Oxygen bonds. It also stated that these C-H bonds were unstable, while the C=O bonds were stable. I'm really confused now because I always thought that stability means unreactive, so according to this book, that would make the C-H bonds reactive. How could this be???
Asked by Nickki - Sun Sep 16 11:30:39 2007 - - 1 Answers - 0 Comments

A. You are right in that a stable bond is unreactive. In this case, you are looking at the relative reactivity of the bonds. A C-H bond is more reactive (unstable) than a C=O bond. This does not mean that a C-H bond reacts easily; it just means that the C=O bond is more stable than a C-H bond.

Asked by Mr. man - Sun Dec 16 23:48:40 2007 - - 3 Answers - 0 Comments

A. To distinguish between an ionic and covalent bond, it is best to examine the electronegativity between of the atoms involved. If the difference of the electronegativities is 1.2, the bond is non-polar covalent, if 1.2 x 1.8, than the bond is polar covalent, if the difference is 1.8, than the bond is ionic. For a bond between hydrogen and oxygen, with respective electronegativities of 2.1 and 3.5, the bond is covalent, as the difference is equal to 1.4.

A. Hydrogen bonding refers to attractions between the hydrogen in one molecule and the anion in another molecule, such as the hydrogen bonding between molecules of water. It's not a chemical bond within a molecule. Covalent bonding occurs within the molecule when the two (or more) bonded atoms share the electrons between them. Again, water is an example of covalent bonding.

I've managed to get bond conditions changed to allow out of state travel but you need a good reason and I'm not sure if they would allow an actual move. You'd need to make sure you have a very good explanation. Since the arraignment has already passed there is no established procedure to address this so I can understand the uncertainty. I would probably suggest that a motion be filed for change in bond conditions. The motion would allow you to get the item before the judge, make your case, and receive a court order. The motion process could be a bit of work but it's not too bad. You may already have other motions pending and they may be… [cont.]

Hydrogen (H) and fluorine (F) form only a single covalent bond each. That means that in order to form a three-atom compound, Se and S are going to have to be the middle atom in each of their respective molecules. Therefore, the shape of that molecule depends entirely upon the nature of the middle atom. Let's start with sulfur. It has four valencies.

A. The leveraged bond fund has used margin (borrowed money) in attempt to increase returns.The income money comes from the issuer of the bonds. The margin holder (or borrower) (in this case the fund) pays interest on the borrowed money. If the cost of margin is low and the yield (interest) is higher on the bonds, there is a net (extra) return on the leveraged fund. However if the leveraged bond fund falls in price, the value of the fund will fall greater than a NON levered fund. A sharp decline (depending on margin requirements) can force the levered fund to either put up more cash or securities to maintain the leveraged amount, or it will be forced to liquidate assets subject to a "margin call."
