Question
Which of the following species contain three bond pairs and one lone pair around the central atom ?
Options
A.H2O
B.BF3
C.NH2-
D.PCl3
Solution
(a) H2O ⇒ 
(b) BF3 ⇒
(c) NH2- ⇒
(d) PCl3 ⇒
Thus, in PCl3, the central atom P has three bond pairs and one lone pair.
(b) BF3 ⇒
(c) NH2- ⇒
(d) PCl3 ⇒
Thus, in PCl3, the central atom P has three bond pairs and one lone pair.
