Bond angle is the angle between the bonded orbitals. Generally, it decreases as the number of lone pair of electrons increases or as the electronegativity of the central atom decreases. Which of the following set of species has same bond angle around central atom?

A)  \[BC{{l}_{3}},\text{ }B{{F}_{3}}\]                 

B)  \[N{{F}_{3}},\,\,N{{H}_{3}}\]

C)  \[AlC{{l}_{3}},\,\,N{{H}_{3}}\]                      

D)  \[{{\operatorname{BeCl}}_{2}},\,\,SnC{{l}_{2}}\]

Correct Answer: A

Solution :

Structure of BC^ and BP^ are as follows
