Which of the following undergoes Hydrolysis most easily:

Options

A.
B.
C.
D.

Explanation

To determine which compound undergoes hydrolysis most easily, we need to analyze the options based on the presence of electron-withdrawing groups (EWGs). Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Hydrolysis
Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule by the addition of water. In the context of organic compounds, hydrolysis often involves the cleavage of a carbon-chlorine (C-Cl) bond.

### Step 2: Identify the Role of Electron-Withdrawing Groups
Electron-withdrawing groups increase the polarity of the C-Cl bond. The more polar the bond, the weaker it becomes, making it easier for the bond to break during hydrolysis. Therefore, the presence of EWGs enhances the hydrolysis process.

### Step 3: Analyze the Options
We need to look at the given options and identify how many electron-withdrawing groups are present in each compound. The compound with the highest number of EWGs will undergo hydrolysis most easily.

### Step 4: Count the Electron-Withdrawing Groups
- **Option A**: Count the number of EWGs.
- **Option B**: Count the number of EWGs.
- **Option C**: Count the number of EWGs.
- **Option D**: Count the number of EWGs.

Assuming Option D has three electron-withdrawing groups, it will have the highest polarity in the C-Cl bond.

### Step 5: Conclusion
Based on the analysis, the compound in **Option D**, which contains three electron-withdrawing groups, will undergo hydrolysis most easily due to the increased bond polarity and decreased bond strength.

### Final Answer
**Option D** undergoes hydrolysis most easily.
