Why cyclopentadiene is acidic

Another example is cyclooctatetraene. Edit: Huckel's Rule: Aromaticity - Antiaromaticity If we look at the energetic positioning of the molecular orbitals MO's in a cyclic, conjugated polyene, we can quickly understand the basis for Huckel's rule. Improve this answer. It comes from the molecular orbital diagrams. See these earlier SE Chem questions, ref1 , ref2. Sign up or log in Sign up using Google. Sign up using Facebook.

Pi bonds are usually weaker than sigma bonds. Quantum mechanics says this is because the orbital paths are parallel so there is much less overlap between the p-orbitals.

Pi bonds happen when two atomic orbitals are in contact through two areas of overlap. Skip to content Common questions. April 23, Joe Ford. Table of Contents.
