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. 

(a) 

(b) 

Answer 1

(a) The bond cleavage using curved-arrows to show the electron flow of the given reaction can be represented as 

It is an example of homolytic cleavage as one of the shared pair in a covalent bond goes with the bonded atom. The reaction intermediate formed is a free radical. 

(b) The bond cleavage using curved-arrows to show the electron flow of the given reaction can be represented as
