Question

$C{H}_{3}N{O}_2$
Sum of no. of $\sigma$ bonds and no. of $\pi$ bonds in the above molecule is :

Answer 1

Nitromethane $C{H}_{3}N{O}_2$ contains 6 $\sigma$ - bonds, 1 $\pi$ - bonds.
$\begin{array}{ccccc}& & \oplus & & \\ H_{3}C& -& N& =& O\\ & & |& & \\ & & O^{⊝}& & \end{array}(6\sigma -bonds,1\pi -bonds)$
