Solution: What is the hybridization of nitrogen in the following molecules? (Type your answer using the format sp2.)HNNHH3CNCH3CNH2 

Problem

What is the hybridization of nitrogen in the following molecules? (Type your answer using the format sp2.)

HNNH

H3CNC

H3CNH

Solution

The nitrogen in HNNH  = sp2 due to double bond to nitrogen, single bond to hydrogen and a lone pair (3 groups)

The nitrogen in H3CNC  = sp due to having a triple bond between nitrogen and carbon and a single bond between nitrogen and the other carbon (2 groups)
