Explain Hoffmann's method to separate ethanamine and N-methylmethanamine from their mixture.
b) What happens when:
i) chloroform is treated with acetone in presence of aq. \( \text{KOH} \)?
ii) ethanal reacts with 2,4–DNP ?
iii) aniline is added to ice-cold solution of sodium nitrite and hydrochloric acid?
iv) Nitro-benzene is subjected to electrolytic reduction ?
OR
a) Identify\( \text{A}, \text{B}, \text{C} and \text{D} \) in the following reaction sequence.
\( \text{A} \xrightarrow[\Delta]{\text{NaOH} + \text{CaO}} \text{B} \xrightarrow{\text{CHCl}_3 / \text{AlCl}_3} \text{C} \xrightarrow{[\text{O}]}{\text{CrO}_2\text{Cl}_2 / \text{H}^+} \text{D} \)
Compound 'C' can be obtained by Clemmensen's reduction of benzaldehyde.
b) Explain the test of propan-1-ol and propan-2-ol by using Victor-Meyer's method in detail.
