The shape of the hydrides of group VA elements is:

A)  square planar   

B)         pyramidal

C)  tetrahedral     

D)                         trigonal planar

Correct Answer: B

Solution :

Hydrides of VA elements (\[N{{H}_{3}},\,P{{H}_{3}}\]etc.) have pyramidal structures. The central atoms in these undergo \[s{{p}^{3}}\text{-}\]hybridisation and these are surrounded by \[3\sigma bps\] and \[1-lps\].
