$CH_3 COCH_3 \quad C_2 H_6 \quad (CH_3 CO)_2 O$

Vedclass · Answer

(C) Reaction $(I)$: Dry distillation of calcium acetate gives acetone $(CH_3 COCH_3)$ and calcium carbonate $(CaCO_3)$. Thus,$\underline{A} = CH_3 COCH_3$.Reaction $(II)$: Reduction of acetic acid with $HI$ and red phosphorus gives ethane $(C_2 H_6)$. Thus,$\underline{B} = C_2 H_6$.Reaction $(III)$: Dehydration of acetic acid with $P_4 O_{10}$ gives acetic anhydride $((CH_3 CO)_2 O)$. Thus,$\underline{C} = (CH_3 CO)_2 O$.Therefore,the correct sequence is $\underline{A} = CH_3 COCH_3$,$\underline{B} = C_2 H_6$,and $\underline{C} = (CH_3 CO)_2 O$.
