Question

Heterolysis of carbon-chlorine bond produces

• A. Two free radicals
• B. Two carbonium ions
• C. Two carbanions
• D. One cation and one anion

Answer 1

The correct option is D One cation and one anion

The tendency for heterolytic cleavage is determined by the electronegativity difference between the atoms joined by the bond.
In $C-Cl$ there is much electronegative difference between C & Cl and hence $C-Cl$ bond will undergoes heterolytic cleavage.
$C-Cl\underset{\text{bond fission}}{\overset{Heterolytic}{\to }}\underset{\text{Cation}}{C^{+}}+\underset{\text{Anion}}{C{l}^{-}}|$
