The standard molar enthalpies of formation of cyclohexane (l) and benzene (l) at `25^(@)C` are `-156` and `+49 kJ mol^(-1)`, respectively. The standard enthaly of hydrogenation of cyclohenxene (l) at `25^(@)C` is `-119 kJ mol^(-1)` Use this data to estimate the magnitude of the resonance enegry of benzene.

Explanation

To estimate the magnitude of the resonance energy of benzene, we can follow these steps:

### Step 1: Write the Formation Reactions
We start by writing the formation reactions for cyclohexane (C6H12) and benzene (C6H6):

1. For cyclohexane:
\[
6C + 6H_2 \rightarrow C_6H_{12} \quad \Delta H = -156 \, \text{kJ/mol}
