🤓 Based on our data, we think this question is relevant for Professor Ratliff's class at USF.

Solution: One resonance structure of the nitrate ion isThe bond angles in this ion are 120 .Is this observation consistent with the preceding discussion of the effect of multiple bonds on bond angles?

Problem

One resonance structure of the nitrate ion is

N is double bonded above to O, which has two pairs of dots, and single bonded below, angled left and right, to two Os, which each have three pairs.  The entire molecule has a negative charge.

The bond angles in this ion are 120 .

Is this observation consistent with the preceding discussion of the effect of multiple bonds on bond angles?
