WebAug 25, 2024 · An isolated double bond is a chemical bond that is made of a sigma bond and a pi bond. Usually, this term is used when the double bonds in an organic structure are not arranged in an alternating pattern with the single bonds. In other words, isolated double bonds have two or more single bonds between them and are arranged in a random manner. WebSp³, sp² and sp hybridization, or the mixing of s and p orbitals which allows us to create sigma and pi bonds, is a topic we usually think we understand, only to get confused when it reappears in organic chemistry molecules and reactions.
