Question

In which of the following, homolytic bond fission takes place?

• A. Hydrolysis of ethyl chloride
• B. Nitration of Benzene
• C. Addition of HBr to double bond
• D. Free radical chlorination of methane

Answer 1

The correct option is D Free radical chlorination of methane

In Free radical chlorination of methane, homolytic bond fission takes place.
The bond pair of electrons is equally distributed to two atoms, each one getting one electron each $Cl-Cl\to C{l}^{\cdot }+C{l}^{\cdot }$
In all other given reactions, an ionic mechanism is followed.
