A) \[NH_{2}^{-}>N{{H}_{3}}>NH_{4}^{+}\]
B) \[NH_{4}^{+}>N{{H}_{3}}>NH_{2}^{-}\]
C) \[N{{H}_{3}}>NH_{2}^{-}>NH_{4}^{+}\]
D) \[N{{H}_{3}}>NH_{4}^{+}>NH_{2}^{-}\]
Correct Answer: B
Solution :
The order of bond angles is \[NH_{4}^{+}>N{{H}_{3}}>NH_{2}^{-}\] because \[NH_{4}^{+}\] has no lone pair, \[N{{H}_{3}}\] has one lone pair while \[NH_{2}^{-}\]has two lone pairs to repel the bond pairs.You need to login to perform this action.
