Solution
The correct option is ACH3COCH3 and CH3CCl2CH3 The first reaction is Kucherov reaction, which involves the hydration of propene with 1 % mercuric sulphate and dil. sulphuric acid to form 2-propenol which then tautomerizes to propanone which is the compound A. CH3C≡CHaqH2SO4−−−−−→HgSO4CH3COH=CH2tautomerization−−−−−−−−−−→CH3COCH3(A) In the second reaction, the O atom of the CO group is replaced with 2 Cl atoms to form compound B. CH3COCH3+PCl5heat−−→CH3CCl2CH3(B)+POCl3
