What is the resonance structure for C_6H_6? - Socratic
Apr 27, 2015 · The following diagram represents the resonance structures of benzene, "C"_6"H"_6". The circle inside the benzene ring on the right indicates that all C-C bonds are equal. The following diagram shows a different way that a benzene ring is represented that you may see in your studies. The carbon atoms at the six points are not drawn, but are understood …
How can I determine if and when a molecule has or needs a …
Jan 3, 2014 · A molecule can have resonance structures when it has a lone pair or a double bond on the atom next to a double bond. Whenever you can draw two or more Lewis structures for a molecule, differing only in the locations of the electrons, the actual structure is none of the structures but is a resonance hybrid of them all. For example, what is the Lewis structure of …
Resonance - Chemistry - Socratic
Resonance refers to the existence of numerous forms of a compound, and is a component of valence bond theory. Shown below are the two resonance structures of benzene: These appear to be simple mirror images of each other, but this in fact represents a process that occurs continuously throughout the lifetime of a benzene ring.
What are two possible resonance structures for benzene?
May 4, 2015 · There are only two possible resonance structures of the Benzene ring. The double bonds (there are three in total) just move one place forward or backward, whichever way you want to look at it. Image from: As you can see in the diagram the double bonds (two lines connecting the C's) are in a specific place, so the other resonance structure would be where the double …
What are all resonance structures for SO3? - Socratic
Sep 22, 2014 · There are seven resonance structures for "SO"_3. > When you draw the Lewis structure, you first get the three structures at the top. In each of them, "S" has a formal charge of +2 and two of the "O" atoms have formal charges of -1. In each of the three structures in the middle, "S" has a formal charge of +1 and one of the "O" atoms has a formal charge of -1. In …
How can I calculate the bond order of benzene? - Socratic
Apr 11, 2014 · You draw the molecular orbitals. Then you add electrons and count the number of bonding and antibonding electrons. The bond order of a bond is half the difference between the number of bonding and antibonding electrons. BO = ½(B – A) The C-C σ Bonds Each C-C σ bond is a localized bond. It has 2 bonding electrons and 0 nonbonding electrons. σ BO = ½(B – A) = …
Which one of the following is expected to exhibit resonance? (A)
Jun 28, 2015 · The expected answer is probably D) "NO"_2^-. Both "CO"_2 and "HCN" also exhibit resonance, but they have only one major contributor. "CO"_2 has two major contributors. To determine if resonance is possible, you draw the Lewis structure and then see if you can put the electrons in different locations. A) "CO"_2 The Lewis structure for "CO"_2 is There are two …
What are the resonance structures for CO_3^-2? - Socratic
Jan 27, 2017 · This is a carbonate ion. A resonance structure means that there are more than one way to draw the ion. First, determine the total number of electrons available: 1 Carbon - 4 3 Oxygen - 6(3) = 18 And the charge of -2 gives you an additional 2 electrons. Hence, there are 24 electrons in total (4+18+2=24) Carbon would be in the middle which gives you However, note …
What are the rules for drawing resonance structures?
Nov 24, 2014 · The rules for drawing resonance structures are: > You can never move atoms. You can move only π electrons or lone pairs that are in p orbitals. All resonance structures must have the same number of valence electrons. You can never move atoms If atoms move, we have isomers, not resonance contributors. The structures above are resonance contributors, …
What is the resonance structure of carbon dioxide? | Socratic
Feb 7, 2015 · Carbon dioxide, or "CO"_2, has three resonance structures, out of which one is a major contributor. The "CO"_2 molecule has a total of 16 valence electrons - 4 from carbon and 6 from each oxygen atom. Here are the three resonance structures for "CO"_2, all accounting for the 16 valence electrons The atoms in all three resonance structures have full octets; …
