Electron withdrawing group (–NO2) increases the acidity while electron releasing group (–CH3–H) decreases acidity. Also, effect will be more if functional group is present at para position than ortho and meta position.

1. Electron withdrawing group (–NO2) increases the acidity while electron releasing group (–CH3–H) decreases acidity.
2. Electron releasing group (–CH3–H) increases acidity while electron withdrawing group (–NO2) decreases acidity.
3. Electron withdrawing group (–CH3–H) decreases acidity while electron releasing group (–NO2) increases acidity.
4. Electron releasing group (–NO2) decreases acidity while electron withdrawing group (–CH3–H) increases acidity.

Correct answer: Electron withdrawing group (–NO2) increases the acidity while electron releasing group (–CH3–H) decreases acidity.

Solution

Electron withdrawing groups like –NO2 stabilize the conjugate base by delocalizing negative charge, increasing acidity. Conversely, electron releasing groups like –CH3 destabilize the conjugate base, decreasing acidity.
