Solution

The correct option is C $Z$ is $C H_{3} C H_{2} C H_{2} O H$
$C H_{3} C H_{2} I K C N - -- \to C H_{3} C H_{2} C N (X) H_{2} O, H^{+} - ---- \to e x c e s s C H_{3} C H_{2} C O O H L i A l H_{4} - --- \to C H_{3} C H_{2} C H_{2} O H$
$Z$ is $C H_{3} C H_{2} C H_{2} O H$ which cannot give the iodoform test.
