Question

A bond cleavage can occur by two ways homolytic and hetrolytic when CH4, undergoes in heterolytic cleavage then total
number of electron in CH2(2-), is :​

Answer 1

Homolytic cleavage is the breaking of a covalent bond in such a way that each fragment gets one of the shared electrons.

The word homolytic comes from the Greek homoios, "equal", and lysis, "loosening".

For example, the homolytic cleavage of a Br-Br bond is

Homolytic cleavage produces free radicals — atoms with unpaired valence electrons

Bond cleavage is the splitting of a chemical bond.

There are two types of bond cleavage: homolytic and heterolytic.

In homolytic cleavage, the two electrons in the bond are divided equally between the products.

In heterolytic cleavage, one atom gets both of the shared electrons.
