Question

In a standard molecule of toluene ($C_6H_5CH_3$), how many individual C-H $\sigma$ -bonds of the alkyl group can effectively participate in hyperconjugation, donating electron density directly into the aromatic $\pi$ system to activate the ring?

Prashant Kotian · Accepted Answer

Correct answer: 3. Toluene consists of a methyl group directly attached to an hybridized carbon of a benzene ring. The methyl group possesses exactly 3 -hydrogens. The -electrons from all 3 of these C-H bonds can overlap with the adjacent -system of the aromatic ring, yielding 3 hyperconjugative forms.
