Question

For the following bond cleavages, use curved-arrows to show the electron flow and classify each as homolysis or heterolysis. Identify reactive intermediate produced as free radical, carbocation and carbanion:

$H_{3} C O - O C H_{3} ⟶ C H_{3} ˙ O + ˙ O C H_{3}$

Solution

This is an example of homolytic fission. The bond pair of electrons is equally distributed between two atoms. Free radicals are formed as reaction intermediates.
