Vedclass · Answer

(C) The reaction involves the thermal decarboxylation of $\beta$-dicarboxylic acids. For the $cis$-isomer,the two carboxylic acid groups are on the same side of the ring. Upon heating,decarboxylation can occur from either of the two equivalent carboxylic acid groups,leading to the formation of two possible stereoisomeric products (diastereomers) depending on the relative orientation of the remaining group and the bromine atoms. For the $trans$-isomer,the two carboxylic acid groups are on opposite sides of the ring. Due to the specific geometry and the requirement for a cyclic transition state,decarboxylation leads to a single specific product. Therefore,the number of possible products for $x$ is $2$ and for $y$ is $1$.

The products obtained in the given reactions are shown below. The number of possible products for $x$ and $y$ are:
