A) \[P{{H}_{3}}>As{{H}_{3}}>Sb{{H}_{3}}>N{{H}_{3}}\]
B) \[~N{{H}_{3}}>P{{H}_{3}}>As{{H}_{3}}>Sb{{H}_{3}}\]
C) \[As{{H}_{3}}>Sb{{H}_{3}}\text{ }>P{{H}_{3}}>N{{H}_{3}}\]
D) \[Sb{{H}_{3}}>As{{H}_{3}}>P{{H}_{3}}>N{{H}_{3}}\]
Correct Answer: B
Solution :
As the basic strength of hydride decreases while on moving down the group so the correct order is as follows: \[N{{H}_{3}}>P{{H}_{3}}>As{{H}_{3}}>Sb{{H}_{3}}\] Hence, the correct option is [b].
