state Hückel's rule​

Answer 1

in 1931 german chemist and physicist Erich huckel proposed a theory to help determine if a planner ring molecule would have aromatic properties . he rule state that if a cyclic, planer molecule 4n+2π electrons it is considered molecule . its a huckels rule ...

Answer 2

HUCKEL'S RULE

• It states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.

• This rule would come to be known as Hückel's Rule.

In order to be aromatic, a molecule must have a certain number of pi electrons (electrons with pi bonds, or lone pairs within p orbitals) within a closed loop of parallel, adjacent p orbitals.

EXAMPLE

The best-known example is benzene (C₆H₆) with a conjugated system of six π electrons, which equals 4n + 2 for n = 1.
