Free radical aromatic substitution - Hydrocarbon
The aromatic substitution reactions that follow free radical mechanisms are extremely few and have limited synthetic value. Although some typical illustartions of these reactions are:
The method of chlorination of benzene at high temperature is identical to that of the free radical aliphatic substitution
Cl2 → Cl + Cl (Chain initiation)
C6H6 + Cl → C6H5+HCl (H- abstraction)
C6H5 + Cl2 → C6H5Cl + Cl (Chain propagation)
The correct order of increasing energy of atomic orbitals is: (1) 5p (2) 5p (3) 4f (4) 5p Ans: 5p
