The bond angles of N H 3 , N H 4 + and N H 2 - are in the order
Options
- AN H 2 - > N H 3 > N H 4 +
- BN H 4 + > N H 3 > N H 2 -
- CN H 3 > N H 2 - > N H 4 +
- DN H > N H 4 + > N H 2 -
Correct answer
B. N H 4 + > N H 3 > N H 2 -
Step-by-step solution
As the number of lone pairs of electrons increases, bond angle decreases. Thus, the order of bond angle is N H 4 + > N H 3 > N H 2 - no Ip 1 Ip 2 IP
