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$:\ 4>3>2>1.$
