Question

Choose the correct statement(s):

• A. Anti-aromatic compounds are more stable than aromatic compounds.
• B. Anti-aromatic compounds have more electrons in bonding molecular orbitals.
• C. Aromatic compounds have more electrons in bonding molecular orbitals.
• D. Non-aromatic compounds are more stable than anti-aromatic compounds.

Answer 1

Answer: (C), (D)

The correct options are
C Aromatic compounds have more electrons in bonding molecular orbitals.
D Non-aromatic compounds are more stable than anti-aromatic compounds.

Stability order :
Aromatic> Non-aromatic>Anti-Aromatic
Anti-aromatic compounds have more electrons in antibonding molecular orbitals.
So, energy increases and stability decreases.
Aromatic compounds have more electrons in bonding molecular orbitals.
So, energy decreases and stability increases.
