Definitions:

Pentadienyl Anion

A negatively charged ion formed by removing a proton from a pentadiene, featuring five carbon atoms connected with alternating single and double bonds.

Bonding π Molecular Orbital

A type of molecular orbital that forms when p-orbitals overlap linearly, allowing for the delocalization of π electrons across adjacent atoms.

Allyl Anion

A negatively charged species featuring a carbon atom adjacent to a double bond, important in organic reactions.

Major Product

The product that is formed in the greatest amount from a chemical reaction, determined by the reaction's mechanism and conditions, including temperature and pressure.
