In the resonating structures of benzene, the number of `sigma and pi` bonds are:

Options

A. `3pi and 12sigma`
B. `3sigmaand 12 pi`
C. `6piand 6 sigma`
D. `12pi and 12sigma`

Explanation

To determine the number of sigma (σ) and pi (π) bonds in the resonating structures of benzene, we can follow these steps:

### Step-by-Step Solution:

1. **Draw the Structure of Benzene:**
- Benzene (C₆H₆) has a hexagonal ring structure with alternating double bonds. Each carbon atom is bonded to one hydrogen atom.

2. **Identify the Types of Bonds:**
- In benzene, there are both single and double bonds. Each carbon-carbon single bond is a sigma bond, and each carbon-carbon double bond consists of one sigma bond and one pi bond.

3. **Count the Sigma Bonds:**
- Count the single bonds between carbon atoms and the bonds between carbon and hydrogen atoms.
- There are 6 carbon-carbon single bonds (C-C) and 6 carbon-hydrogen (C-H) bonds.
- Total sigma bonds from C-C: 6 (since each C-C bond is a sigma bond).
- Total sigma bonds from C-H: 6 (since each C-H bond is also a sigma bond).
- Therefore, total sigma bonds = 6 (C-C) + 6 (C-H) = 12 sigma bonds.

4. **Count the Pi Bonds:**
- Each double bond contributes one pi bond. In benzene, there are 3 double bonds.
- Therefore, total pi bonds = 3 (one for each double bond).

5. **Final Count:**
- Total sigma bonds = 12
- Total pi bonds = 3

### Conclusion:
The number of sigma and pi bonds in the resonating structures of benzene is:
- **Sigma bonds (σ): 12**
- **Pi bonds (π): 3**
