Benzene molecule has

Options

A. `6sigma` and `6pi` bonds
B. `16sigma` and `6 pi` bonds
C. `12 sigma` and `3pi` bonds
D. `6sigma` and `3pi` bonds

Explanation

To determine the number of sigma and pi bonds in a benzene molecule, we can follow these steps:

### Step 1: Understand the Structure of Benzene
Benzene (C6H6) is a cyclic compound consisting of six carbon atoms arranged in a hexagonal ring. Each carbon atom is bonded to one hydrogen atom.

### Step 2: Identify the Bonds
In benzene, there are two types of bonds:
- **Sigma (σ) bonds**: These are single covalent bonds formed by the head-on overlapping of atomic orbitals.
- **Pi (π) bonds**: These are formed by the side-to-side overlap of p orbitals and are present in double bonds.

### Step 3: Count the Sigma Bonds
1. Each carbon atom in benzene forms:
- One sigma bond with the adjacent carbon atom (there are 6 carbon-carbon bonds).
- One sigma bond with a hydrogen atom (there are 6 hydrogen atoms).

Therefore, the total number of sigma bonds is:
- Carbon-Carbon sigma bonds: 6
- Carbon-Hydrogen sigma bonds: 6

Total sigma bonds = 6 (C-C) + 6 (C-H) = **12 sigma bonds**.

### Step 4: Count the Pi Bonds
Benzene has alternating double bonds, which means:
- There are 3 pi bonds formed between the carbon atoms in the benzene ring.

### Step 5: Summarize the Results
- Total Sigma Bonds: 12
- Total Pi Bonds: 3

### Final Answer
In a benzene molecule, there are **12 sigma bonds and 3 pi bonds**.
