Chemistry - GOC Question with Solution | TestHub

An electrophilic center is electron-deficient and accepts electrons.

In (A) HCHO, carbonyl carbon is electrophilic due to polar C=O bond.

In (B) CO₂, central carbon is also electrophilic because of electron-withdrawing O atoms.

In (C) CH₂=NH, carbon attached to electronegative N shows partial positive charge → electrophilic.

In (D) CH₃MgBr (Grignard reagent), carbon is nucleophilic (carbanion-like), not electrophilic.

Hence, carbon does not act as electrophilic centre in (D).
