Benzene is unusually stable due to:

A Sigma bonds only

B Electron delocalization (resonance/aromaticity)

C Ionic character

D High molecular weight

✓ Correct Answer: Option B

Benzene 6 pi electrons are delocalized across the ring (aromaticity), providing extra thermodynamic stability beyond what isolated double bonds would give.

💡 Why is B) the correct answer?

The correct answer to the question "Benzene is unusually stable due to:" is Option B: Electron delocalization (resonance/aromaticity).

The other options — A) Sigma bonds only, C) Ionic character, D) High molecular weight — are incorrect for this MCAT Exam Prep question. As explained above: Benzene 6 pi electrons are delocalized across the ring (aromaticity), providing extra thermodynamic stability beyond what isolated double bonds would give.
