A hydrocarbon (A) (molecular formula (`C_(5)H_(10)`) yields 2-methyl butane on catalytic hydrogenation. (A) adds HBr (in accordance with Markonikov's rule) to form a compound (B), which on reaction with silver hydroxide forms an alcohol ( C ), `C_(5)H_(12)O`. Alcohol ( C ) on oxidation gives a ketone (D). Deduce the structure of (A), (B), ( C ) and (D) and show the reactions involved.
