Question

In benzene, the triple bond consists of

• A. one \( sp^2 - sp^2 \) sigma bond and two \( p - p \) pi bonds
• B. two \( sp^2 - sp^2 \) sigma bonds and one \( p - p \) pi bond
• C. one \( sp^2 - sp^2 \) sigma bond, one \( p - p \) pi bond and one \( p - p \) pi bond
• D. None of the above

Hint:

In conjugated systems like benzene, the bonds between carbon atoms are delocalized, contributing to the stability of the structure.

Answer 1

The Correct Option is C

In the triple bond of benzene, the \( sp^2 - sp^2 \) sigma bond is formed by overlapping of the hybridized orbitals and the \( p - p \) bonds are the pi bonds formed by sideways overlapping of unhybridized p-orbitals. Benzene has a resonance structure, which means it is a conjugated system with delocalized electrons.
