A Hydrocarbon X (M.F.`C_4H_6`) produces an aldehyde Y through Hydrocarbon Oxidation and a ketone Z through Oxymercuration Demercuration. Y and Z are functional isomers. X gives P when treated with excess of HOCl and Q when treated with excess of HCl.
The correct statement is :
A. P and Q are positional isomers
B. Q is 1,2-Dichlorobutane
C. P is 1,1-Dichlorobutan-2-one
D. P and Q are identical
