When 1,1-dichloropropane and 2,2-dichloro propane are reacted separately with aqueous potassium hydroxide solution, compounds A and B are formed. Both A and B gave the same product C on reduction using amalga-matedzinc and $HCl$. Identify C.

2, 2-dichloropropane is hydrolyzed to propane-2,2-diol in the presence of $KOH$, which then loses a water molecule to generate acetone (compound A). Acetone is reduced by Clemmensen to propane in the presence of $Zn$/$Hg$and concentrated $HCl$(compound B). Methylene group is created by reducing a carbonyl group.he product C is given in the above figure. Some in the case of 1,1 – dichloropropane.

Hence , the correct option is (D).Propane.
