The largest bond angle is in         [DCE 2002; MNR 1984]

A)                 \[As{{H}_{3}}\] 

B)                 \[N{{H}_{3}}\]

C)                 \[{{H}_{2}}O\]  

D)                 \[P{{H}_{3}}\]

Correct Answer: B

Solution :

                                                              As the electronegativity of central atom decreases bond angle is decreases \[\therefore \] \[N{{H}_{3}}\]has largest bond angle.
