MCQ

Dehydration of the following in increasing order is:

✓
$I$
B
$II$
C
$I$
D
$I$

✓

Answer

Correct option: A.

$I$

Phenol $(I)$ is stable aromatic compound. So it is most stable. The diene $(IV)$ undergoes quick dehydration because it will form stable phenol. The alkene $\text{(III)}$ undergoes dehydration. less readily because it gives a more stable diene. Alcohol $(II)$ undergoes much lesser dehydration to form alkene. So, order is$:\ 4>3>2>1.$
