Question

6. What are the criteria for a compound to be classified as aromatic? List them below:

Answer 1

Here is the Solution:

Đ There are satisfied four most structural criteria must be for a compound to be aromatic. . (1). A molecule must be cyclic. To be aromatic, each p orbital must overlap with porbitals on adjacent atom. <Benzene> (2). A molecule must be planar - Like , Benzene is a planar. HC CH Planar molecule is when all atoms of molecule lie in the same plane. conjugated. (3). A molecule must be completely - Aromatic compounds must have a p orbital on every atom, completely conjugated molecule (4). A moleccele must satisfy Huckel's rele, and contain a particular number of the electrons. Huckel's rule states that if a cyclic planar molecule has 4n+2 π electrons, it is considered as aromatic compound.
