- B$HCOO{C_2}{H_5}$ and ${C_3}{H_7}COOC{H_3}$
- C$C{H_3}COOC{H_3}$ and ${C_3}{H_7}OH$
- D${C_3}{H_7}OH$and $C{H_3}COC{H_3}$
$(A) \,HCOOC _2 H _2$ meet formula $= c _3 H _6 O _2$
$CH _3COOCH_3$ Meet formula $= C _3 H _6 O _2$
Hence, option $A$ is correct.
$(B) \,H - COOC _2 H _5$ and $C _3 H _7COOH$
$HCOOC_2 H _5$ Meet formula $= C _3 H _6 O _2$
$C _3 H _4 COOH$ meet formula $= C _4 H _8 O _2$
Hence, option $B$ is incorrect.
Similarly, options $C$ and $D$ are incorrect.
