Which scientist is associated with the 4n+2 π-electron rule for aromaticity in suitable planar, cyclic, conjugated systems?

Explanation

Erich Hückel is associated with the 4n+2 π-electron rule for aromaticity in suitable planar, cyclic, continuously conjugated systems. Here n is a non-negative integer. The rule concerns π electrons in the conjugated circuit, not every electron or every compound with an odd number of electron pairs.
