Question

Conditions for aromatic non aromatic and antiaromatica

Answer 1

o a non aromatic compound is either not cyclic or not planar. And an anti aromatic compound is cyclic, planar and has the conjugation of p orbitals, but the difference is the number of electrons in the conjugated p orbitals.

So while aromatic molecules have (4n+2) pi electrons, the “rule” for anti aromatic molecules is (4n). ... Anti-aromatic molecules are cyclic, conjugated, have (4n) pi electrons, and are flat. Non-aromatic molecules are every other molecule that fails one of these conditions

Answer 2

Explanation:

• The molecule should be planar.
• the molecule should be cyclic with alternate single and double bond
• The molecule should contain (4n+2)π electron where n= 0,1,2,3,etc.(huckel rule).
• a molecule which does not satisfy any one or more of the above mentioned condition is said to be non aromatic.
