Question

Schemes $1$ and $2$ describe sequential transformation of alkynes $M$ and $N$. Consider only the major products formed in each step for both schemes.

The correct statement with respect to product $Y$ is

• A. It gives a positive Tollens test and is a functional isomer of $X$.
• B. It gives a positive Tollens test and is a geometrical isomer of $X$.
• C. It gives a positive iodoform test and is a functional isomer of $X$.
• D. It gives a positive iodoform test and is a geometrical isomer of $X$.

Answer 1

Answer: (C)

$X$ and $Y$ are functional isomers of each other and $Y$ gives iodoform test.
