Explain the types of addition reactions? |
|
Answer» Solution :Addition REACTIONS are classified into three types. They are, (i) Electrophilic addition reaction. (ii) Nucleophilic addition reaction. (iii) Free radical addition reaction (i) Electrophilic addition reaction: An electrophilc addition reaction can bedescibed as an addition reaction in which a reactant with multiple bonds as in a double or triple bond UNDERGOES has its `pi` bond broken and two new `rho` bond are formed.  (ii) Nucleophilic addition reaction: A nucleophilic addition reaction is an addition reactionwhere a chemical compound with an electron deficient or electrophilic double or triple bond, a `pi` bond, reacts with a nucleophilic which is an electron rich reactant with the disappearance of the double bond and creation of two new single or `rho` bonds.  (iii) Free radical addition reaction: It is an addition reaction in organic chemistryinvolving free radicals. The addition may occur between a radical and a NON radical or between two radicals. `underset ("ETHENE") (CH_(2) =CH_(2)) + H-Br overset("Benzoyl peroxide") to underset ("ETHYL bromide") (CH_(3) - CH_(2)-Br)` |
