`CICH_(2)CH_(2)OH`

Text Solution

Verified by Experts

The correct Answer is:
A
Phenols are more acidic than alcohols on accoount of resonance. Electron withdrawing substituents (such as `-NO_(2)` grooup) increase the acidity of phenols by increasing the stabiliy of phenoxide ion while electron donating substituents (such as - `CH_(3)` group) decrease the acidic strength of phenols by destabilizing the phenoxide ion. Thus, strength of phenols by destabilizing the phenoxide ion. Thus, the decreasing order of acidic strength is
