Heat of hydrogenation of ethene is `x_(1)` and that of benzene is `x_(2)` . Hence resonance energy of benezene is

Options

A. `x_(1) -x_(2)`
B. `x_(1)+x_(2)`
C. `3x_(1)-x_(2)`
D. `x_(1)-3x_(2)`

Explanation

To find the resonance energy of benzene based on the heat of hydrogenation of ethene and benzene, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Heat of Hydrogenation**:
- The heat of hydrogenation is the amount of heat released when hydrogen is added to an alkene or aromatic compound. For ethene (C2H4), the heat of hydrogenation is denoted as \( x_1 \).
- For benzene (C6H6), the heat of hydrogenation is denoted as \( x_2 \).
