JEE Main 8 April 2024, Shift 2, Chemistry Q88

Question 88 of 90 in this shift, Chemistry question 28 of 30, Section B.

Total number of aromatic compounds among the following compounds is ________.

The figure, in words

Six structures in a row: (1) benzene ring fused to a cyclohexane-type six-membered ring (tetralin-like, only the benzene ring has double bonds); (2) two five-membered rings (each with one C=C) joined by a central C=C double bond; (3) cyclopentadienyl cation (five-membered ring with two C=C and a + charge); (4) cyclooctatetraene (eight-membered ring with four C=C); (5) pyridine (six-membered ring with N bearing a lone pair); (6) cycloheptatriene (seven-membered ring with three C=C).
