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.
