An organic compound of molecular formula $C_{6} H_{6} {Br}_{2}$ has six carbon atoms in a ring system, two non-conjugate double bonds and two bromo groups at $1, 4$ positions. Then the compound is

A aromatic but non-homo-cyclic
B aromatic and hetero-cyclic
C homo-cyclic but not aromatic
D neither homo-cyclic nor hetero-cyclic

Verified Solution

Answer & Solution

Correct Answer

(C) homo-cyclic but not aromatic

Step-by-step Solution

Detailed explanation

C6H6Br2:- Double bond equivalent formula = C-H2-X2+1 C=6; H=6;X=2 DBU=6-62-22+1=6-4+1=3 So, it has one ring with two double bonds. It has the two bromo groups at the 1,4 position and has the six membered carbon ring with non-conjugated double bond. Hence, the structure of…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
