The correct statement  with respect to  product Y is


A) I t gives a positive Tollen's test and is a functional isomer of x

B) it gives a positive Tollen's test an 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:

Option C

Explanation:

Plan  This problem can be solved by using the concept of iodoform test and functional isomerism. The compound containing  -COCH3  or -CH(OH) 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 CH3CHO group as indicated

 Hence, correct choice is (c)
