Question

Number of $\pi$ electrons present in naphthalene is

• A. 4
• B. 6
• C. 10
• D. 14

Hint:

Aromatic compounds follow Huckel’s rule: \(4n+2\) $\pi$ electrons.

Answer 1

The Correct Option is C

Concept: Each double bond contributes 2 $\pi$ electrons.

Step 1: Structure of naphthalene.
Naphthalene has 5 double bonds.

Step 2: Count electrons.
\[ \pi \text{ electrons} = 5 \times 2 = 10 \]
