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.

• A. It gives a positive Tollen’s test and is a functional isomer of X
• B. It gives a positive Tollen’s 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

The correct option is C It gives a positive iodoform test and is a functional isomer of X

This problem can be solved by using the concept of iodoform test and functional isomerism.
Iodoform test - The compound containing - $COC{H}_3$
or $-CH\left(OH\right)$ group will undergo iodoform test.

Thus, X and Y are functional isomers of each other and Y gives iodoform test due to the presence of $C{H}_{3}CO$ group as indicated. Hence, correct choice is (c).
The correct statement with respect to product Y is
