Question

In the formation of adduct from ammonia and boron trifluoride.

• A. Hybridization of B is unchanged, but hybridization of N is changed
• B. Hybridization of N is unchanged, But hybridization of B is changed
• C. Hybridization both B and N are unchanged.
• D. Hybridization of both B and N are changed

Answer 1

The correct option is B

Hybridization of N is unchanged, But hybridization of B is changed

Hybridisation of B in $B{F}_3$ is $s{p}^2$
Hybridisation of N in $N{H}_{3}iss{p}^3$
Hybridisation of B in $H_{3}N.B{F}_3$ is $s{p}^3$
Hybridisation of N in $H_{3}N.B{F}_3$ is $s{p}^3$
