The best sequence of reaction to prepare 3 - chloro aniline from benzene is
Nitration, Chlorination, reduction
Nitration, reduction, chlorination
Nitration, reduction, acylation , chlorination, hydrolysis
Chlorination, nitration reduction
NO2 is m - directing group
When Aniline is treated with Nitrous acid, which is prepared
in situ
from Sodium Nitrite and mineral acid, the product formed is:
C6H5NH2+HCl+NaNO2→ _____________ + 2H2O
