Question

An aromatic compound will
(A) have (4n+2) \(\pi\) electrons
(B) be conjugated
(C) be planar
(D) be cyclic
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (B), (C) and (D) only
• C. (A), (B), (C) and (D)
• D. (A), (B) and (C) only

Hint:

Aromatic compounds follow Huckel’s rule: cyclic, planar, conjugated, with \( (4n+2)\pi \) electrons.

Answer 1

The Correct Option is C

Step 1: Recall Huckel’s rule.
For aromaticity, a compound must have \( (4n+2) \pi \) electrons (\(n=0,1,2,...\)).
Step 2: Structural requirements.
- Must be cyclic.
- Must be fully conjugated (p-orbitals overlap).
- Must be planar (allowing delocalization).
Step 3: Evaluate statements.
All four conditions (A, B, C, D) are required for aromaticity.
Final Answer: \[ \boxed{\text{(A), (B), (C) and (D)}} \]
