An organic compound (A) contains 69.77% carbon, 11.63% hydrogen, and rest oxygen. The molecular mass of the compound is 86. It does not reduce Tollens’ reagent but forms an addition compound with sodium hydrogen sulphite and gives a positive iodoform test. On vigorous oxidation, it gives ethanoic and propanoic acid. Compound A would be:
1. Pentan-2-one
2. Butanone
3. 3-Methylbutanone
4. Propan-2-ol
The correct sequence of increasing orders of reactivity in nucleophilic addition reaction is:
1. Butanone < Propanone < Propanal < Ethanal
2. Butanone > Propanone > Propanal > Ethanal
3. Butanone < Propanal < Propanone < Ethanal
4. Propanal < Propanone < Ethanal < Butanone
