# V. quick bond angle question?

Announcements Posted on

1. Say if there was a nitrogen, and oxygen and another nitrogen attached to a carbon. The oxygen forms a double bond.
Would that mean, there are 4 groups of electrons around the carbon or three in determining the bond angle? I'm thinking you take the double bond as 1 so you have 3 groups of electrons so the bond angle would be 120 ?

Tried to illustrate here:

N---C===O

N

Thanks!

Illustration failed! Basically that N at the bottom is bonded to Carbon via single bond.

I think it would be three sets of bonding electrons to consider (one double bond from the oxygen and the two single bonds from the nitrogen). Because the oxygen is a double bond, I think the angle between the two nitrogens would be slightly smaller than 120, but not sure whether the double bond between the nitrogen atoms would constrain how small/large the bond is. Im not too sure, but I think it would be roughly trigonal planar with respect to the carbon atom.

The bond angle would be 120o, as you treat the C=O double bond as a single bond, as there are only 3 R groups
