How many `sigma- and pi-` bonds are present in naphthalene?

Explanation

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

### Step 1: Draw the Structure of Naphthalene
Naphthalene consists of two fused benzene rings. The molecular formula for naphthalene is C₁₀H₈.

### Step 2: Identify the Sigma Bonds
Sigma bonds are formed by the head-on overlap of atomic orbitals. In naphthalene, we have:
- Each carbon atom forms 4 bonds (3 with neighboring carbon atoms and 1 with hydrogen).
