Ketones \((R - \mathop C\limits_{\mathop {||}\limits_O } - {R_1})\) where \(R = {R_1} = \) alkyl group. It can be obtained in one step by
1 Hydrolysis of esters
2 Oxidation of primary alcohol
3 Oxidation of secondary alcohol
4 Reaction of acid halide with alcohols
Explanation:
Since primary alcohol upon oxidation gives only aldehyde whereas ketone can only be obtained from secondary alcohol. Esters on hydrolysis gives acids and alcohol.

Predict the product \(‘B’\) in the sequence of reaction\(HC \equiv CH\mathop {\xrightarrow{{30\%\, {H_2}S{O_4}}}}\limits_{HgS{O_4}} A\xrightarrow{{NaOH}}B\)
Compound A is acetaldehyde and compound \(B\) is \(3-\)hydroxybutanal. \(A\) molecule of water is added to acetylene to form vinylic alcohol which tautomerizes to acetaldehyde. This is followed by aldol condensation to form \(3^{-}\) hydroxybutanal.
