Q

Describe how to analyze bond length

A
  1. Atomic size: larger atoms have longer bonds
  2. Triple bond is shorter than a double bond, which is shorter than a single bond
  3. Fraction of s character in the bond:

more s character: shorter bond

less s character: longer bond

Q

Define the criteria for evaluating if a structure is a legitimate contributing resonance structure

A
  1. Contributing structures with two formal charges in which the more electronegative element bears the positive charge and the less electronegative element bears the negative charge are rarely considered.
  2. Contributing structures with incomplete octets on very electronegative elements such as N, O, F, and Cl are rarely considered.
  3. Contributing structures with formal charges greater than +1 or -1 are rarely considered.
  4. Contributing structures in which there is an expanded octet on H, C, N, O, or F are never considered.

37
Q

Describe the VSEPR analysis for non-ideal bond angles

A
  1. lone pairs are larger than bonded pairs (i.e. lessens the bond angles between other subsituents)
  2. multiple bonds are bigger than single bonds (i.e. lessens the bond angles between other substituents)
  3. Electron pair in an electronegative atom may be further away, increasing bond angles of the other substituents
