JEE Mains · Chemistry · STD 11 - 8.1. Organic chemistry Nomenclature of organic compounds
The total number of aromatic compounds/species from the following is
- A \(6\)
- B \(4\)
- C \(3\)
- D \(5\)
Answer & Solution
Correct Answer
(B) \(4\)
Step-by-step Solution
Detailed explanation
A species is aromatic if it is cyclic, planar, fully conjugated (continuous cyclic overlap of \(p\)-orbitals) and contains \((4n + 2)\,\pi\) electrons (Huckel's rule). Let us analyse each species. \(1,4\)-Benzoquinone: The six-membered ring has only \(4\pi\) electrons (from the…
