Which of the following will be hydrolysed with warm water

Options

A. Chlorobenzene
B. p-Nitrochlorobenzene
C. 2,4-Dinitrochlorobenzene
D. 2,4,6-Trinitrochlorobenzene

Explanation

To determine which compound will be hydrolyzed with warm water, we need to analyze the presence of electron-withdrawing groups in the given options. Hydrolysis is facilitated by nucleophilic substitution, which is more effective when there are strong electron-withdrawing groups present.

### Step-by-Step Solution:

1. **Identify the Compounds**:
Let's denote the compounds as follows:
- Option A: Compound with one chlorine group.
- Option B: Compound with one nitro group.
- Option C: Compound with two nitro groups.
- Option D: Compound with three nitro groups.

2. **Analyze Electron-Withdrawing Groups**:
- Chlorine (Cl) is an electron-withdrawing group but is not as strong as nitro (NO2).
- Nitro groups (NO2) are strong electron-withdrawing groups due to their resonance and inductive effects.

3. **Count the Electron-Withdrawing Groups**:
- Option A: 1 Cl (1 electron-withdrawing group)
- Option B: 1 NO2 (1 electron-withdrawing group)
- Option C: 2 NO2 (2 electron-withdrawing groups)
- Option D: 3 NO2 (3 electron-withdrawing groups)

4. **Determine the Effect on Nucleophilic Substitution**:
The more electron-withdrawing groups present, the easier the nucleophilic substitution will be. Thus:
- Option D, with three NO2 groups, will facilitate hydrolysis the most.

5. **Conclusion**:
The compound that will be hydrolyzed with warm water is the one with the most electron-withdrawing groups, which is **Option D** (three NO2 groups).

### Final Answer:
**Option D** will be hydrolyzed with warm water.
