Question

Correct statement regarding this reaction
$B{F}_3+N{H}_3\to [F_{3}B\leftarrow N{H}_3]$

• A. Hybridiration of $N$ is changed
• B. Hybridiration of $B$ is changed
• C. $N{H}_3$ act as a Lewis Base
• D. $\left(2\right)$ & $\left(3\right)$ both

Answer 1

The correct option is D $\left(2\right)$ & $\left(3\right)$ both

As the transformation takes place, $B$ changes from $s{p}^2$ to $s{p}^3$ dur to the extra coordination by ammonia. Ammonia being a donor is a lewis base.
