Question

Convert:
1) acetyl chloride to ethane
2) ethane nitrile to methane
3) acetaldehyde to but-2-enal
4) propanamide to propyl amine
5) acetyl chloride to butanone
6) propan-2-ol to acetylene

Answer 1

Answer:

(i) Ethanal into Butane-1,3-diol

Aldol condensation (in presence of dil NaOH) followed by reduction with sodium borohydride.

(ii) Ethanal into But-2-enal

Aldol condensation (in presence of dil NaOH) followed by dehydration.

(iii) Ethanal into But-2-enoic acid

Aldol condensation (in presence of dil NaOH) followed by dehydration and oxidation with Tollen's reagent
