Question

Resonance in benzene is accompanied by delocalization of $\pi$ electrons. Each $\pi$ electron is attached with

• A. 4 carbons
• B. 2 carbons
• C. 3 carbons
• D. 6 carbons

Answer 1

The correct option is D 6 carbons

Benzene contains 6 carbon atoms in a ring. Each carbon atom carries a single $\pi$ electron in unhybridized p-orbital.
These 6 electrons are delocalized over the entire ring. Thus, each $\pi$ electron is attached with 6 carbon atoms.
