Predict the products of the following reactions:
i) (the oxidation shown in the figure)
ii) CH–CO–CH →(NaOH/I)→ ? + ?
iii) CHCOONa →(NaOH/CaO, Δ)→ ?
Structure Reaction (i)
Reaction (i)

Solution

(i) The figure's substrate is an alcohol with an oxidising reagent: a 1° alcohol → aldehyde (PCC) or carboxylic acid (strong oxidant); a 2° alcohol → ketone — write the carbonyl product the printed reagent dictates.
(ii) Acetophenone has the CHCO– group — haloform cleavage:

(iii) Soda-lime decarboxylation:
