Which of the following molecule is not aromatic?

Correct answer

3

Step-by-step solution

An aromatic species has planar structure, conjugated C = C double bonds, cyclic structure with all ring carbon atoms with sp ^2 -hybridization and having a total of (4 n+2) electrons. Cycloheptatriene has a total of six - electrons but one ring carbon is sp ^3 - hybridized that restricts the conjugated movement of -electrons. Thus, it is not aromatic.
