1. What is the meaning of bond cleavage?

Answer:

The breaking of a chemical bond is called bond cleavage. There are two types of bond cleavage depending on the sharing of electrons between the two atoms of the bond.

1. Homolytic cleavage: The two electrons in the bond are equally shared between the two atoms.

2. Heterolytic cleavage: One of the atoms gets both the electrons of the bond.
