Question

The total number of electrons in the carbon atom of methyl free radical are:

• A. six
• B. seven
• C. eight
• D. nine

Answer 1

Answer: (B)

seven

Methyl free radical is $\stackrel{.}{C{H}_3}$

$H-\underset{|}{\stackrel{.}{C}}-H$

$H$

Each $C-H$ bond $2e^{-}$ & one unpaired $e^{-}$ on $C$-atom .

$\therefore$ Total electrons present= $3\times 2+1=7$
