Question

Among the following the aromtic compounds is:

Answer 1

Correct option is B.
$$\text{According to Huckel rule for aromaticity, the molecule must be planar, cyclic system having delocalised }$$$$\text{(4nπ+2) electron where n is an integer i. e, 0, 1, 2, 3. Thus, aromatic compounds have 2, 6, 10 or 14π }$$$$\text{electrons. Among yhe following Cyclopropenyl cation (Δ) has 2π electron (n = 0) so, it is aromatic.}$$

$$\text{ Hence, option B is correct.}$$
