Step II: Predicting the
structure of the compound.
Criteria:
1. Formation of addition
compound with depictsthe
presence of aldehyde or ketone.
2. The given compound does not
reduce Tollen's reagent but givespositive iodoform test, so it is a methyl
ketone.
3. On oxidation, the compound
forms a mixture of ethanoic andpropanoic acid, so it is
