MCQ
Compare $\pi -$ bond strength between $B$ and $N$ given in two compounds
$(I)$ $\begin{array}{*{20}{c}}
{{{(C{H_3})}_3}Si - NB{H_2}} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Si{{(C{H_3})}_3}}
\end{array}$ $(II)$ $\begin{array}{*{20}{c}}
{{{(C{H_3})}_3}C - NB{H_2}} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{{(C{H_3})}_3}}
\end{array}$
- AThere is no $\pi $ bond character between $B$ and $N$
- BSame in $I$ and $II$
- C$I > II$
- ✓$II > I$
