Question

In one of the following molecules, the state of hybridization of the control atom is not the same as in the others?

• A. $B$ in $B{F}_3$
• B. $O$ in $H_{2}O$
• C. $N$ in $N{H}_3$
• D. $P$ in $PC{l}_3$

Answer 1

The correct option is A $B$ in $B{F}_3$

$B$ in $B{F}_3$ is $s{p}^2$ hybridised

In $H_{2}O,N{H}_3$ & $PC{l}_3$ the central atom is $s{p}^3$ hybridised.
