The shape of \[N{{H}_{3}}\] molecule is:

A)  tetrahedral      

B)         trigonal planar

C)         trigonal pyramidal          

D)  linear

Correct Answer: C

Solution :

\[N{{H}_{3}}\] is \[s{{p}^{3}}\] hybridised with trigonal pyramidal structure. N atom of \[N{{H}_{3}}\] has a lone pair electron which distorts its geometry due to \[lp-bp\] interaction to reduce the bond angle to \[{{107}^{o}}\].
