2E.17 B

Postby ayushibanerjee06 » Fri Nov 15, 2019 5:07 pm

Can someone explain 2E.17 b)?
The question is: Predict the bond angles at the central atom of the following molecules and ions: (a) ozone, O3; (b) azide ion, N32; (c) cyanate ion, CNO2; (d) hydronium ion, H3O1.

When I draw the structure I get a lone pair on the central N so I thought it would be less than 120.

In the Lewis model the central N has no lone pairs (it is three Ns with the two outside Ns double bonded to the inner N) so it is Linear so the bond angles are 180.

I'm pretty sure there should be two lone pairs on each of the bonded nitrogen atoms while the central nitrogen has a formal charge of +1. The overall charge is still -1 and that way the angle would be 180.
