Chemistry - CHEMICAL BONDING Question with Solution | TestHub

$\mathrm{In}{\mathrm{BF}}_3,\mathrm{B}$ is $s{p}^2$ hybridized with one empty $p_{\mathrm{z}}$ orbital. The empty $p_{\mathrm{z}}$ orbital of ${\mathrm{BF}}_3$ can be filled by lone pair of molecules such as ${\mathrm{NH}}_3$. When this occurs a tetrahedral molecule or ion is formed which is $s{p}^3$ hybridized.
