Expert Answer

Step 1

In organic chemistry, different types of chemical reactions are possible on the basis of their mechanism. Some common mechanism are substitution reaction, addition reaction, elimination reaction and rearrangement reactions.

Step 2

The addition of halogen on C=C is an example of addition reactions as each halogen atom is added on double bonded C atoms to form dihalo-products. The addition of halogen on C=C is always anti-addition in which once halogen added to C=C and form an adduct on which another halogen attack in anti-position.
