Question

Ceric aminonium nitrate and CHCl₃/alc. KOH are used for the identification of functional groups present in ______ and ______ respectively.

Options

• alcohol, phenol 

• amine, phenol

• amine, alcohol 

• alcohol, amine

Answer 1

Ceric aminonium nitrate and CHCl₃/alc. KOH are used for the identification of functional groups present in alcohol and amine respectively.

Explanation:

Ceric ammonium nitrate is used for the identification of alcohol.

\[\ce{2R - OH + (NH4)2 Ce(NO3)6 -> \underset{(Pink or Red colour)}{\underset{Compound}{\underset{Alkoxy cerium ion (IV)}{(ROH)2Ce(NO3)4 +}}} 2NH4NO3}\]

CHCl₃/KOH is used for the identification of primary amines.

\[\ce{R - NH2 + CHCl3 + 3KOH(alc) ->[warm] R - NC + 3KCl + 3H2O}\]
