What is the formal charge on ' $\mathrm{C}$ ' atoms in :

- -1
- -2
- +1
- Zero
Solution
$\text { Formal ch arge }=\left[\begin{array}{l}
\text { Totalno. of } \\
\text { valence }^{-} \\
\text {in freestate }
\end{array}\right]-\left[\begin{array}{l}
\text { Totalno. of } \\
\text { lonepair } \\
\text { electrons }
\end{array}\right]-\frac{1}{2}\left[\begin{array}{l}
\text { no.of bonding } \\
\text { electons on that } \\
\text { particular atoms }
\end{array}\right]$
Formal charge on $\mathrm{C}$-atom $=4-0-\frac{1}{2} \times 8=0$Asked in: MHT CET 2021 (24 Sep Shift 1)
