In which of the following compounds, the C-Cl bond ionisation shall give most stable carbonium ion?

1. H3C-C-Cl
2. H3C-C
3. O2NH2C-C-Cl
4. H3C-C-Cl

Correct answer: O2NH2C-C-Cl

Solution

The compound O2NH2C-C-Cl has an electron-withdrawing nitro group (-NO2) attached to the carbon adjacent to the C-Cl bond. This stabilizes the resulting carbocation through resonance and inductive effects, making it the most stable.
