(b) Give chemical test to distinguish between following pair of
compounds:
(i) Benzaldehyde and Acetophenone
(ii) Ethanal and propanal
(i) Benzoic acid to Benzene:
Benzoic acid is heated with soda lime
(ii) Ethanoyl chloride to Acetone:
React ethanoyl chloride with methylmagnesium bromide
(iii) Acetophenone to Ethyl benzene:
Acetophenone is reduced using Clemmensen reduction
