Assertion : Tropylium cation is aromatic in nature. Reason :The only property that determines its aromatic behaviour is planar structure.

Assertion: Tropylium cation is aromatic in nature. Reason: The only property that determines its aromatic behaviour is planar structure. For the compound to be aromatic, there are 3 conditions which are written as follows- 1. The compound should be cyclic and planar 2. It should have conjugated ring system with alternate double bonds. 3. It should have (4n+2) electrons, where n is an integer. Also,(4 2) electrons =6 4n = 6 2 4n = 4 n = 1 n >> >> It possesses all the above conditions and is aromatic in nature. Thus, the correct option is (c) Assertion is true but Reason is false.
