CH2CHCH2CHCHCH3

The chemical formula CH2CHCH2CHCHCH3 represents a branched alkene. Specifically, it is 2,4-hexadiene. The structure contains a six-carbon chain with two double bonds, located between the second and third carbons, and between the fourth and fifth carbons. The presence of double bonds indicates unsaturation, making it reactive in addition reactions. The molecule exists as geometric isomers due to the double bonds. It can exhibit cis-trans isomerism at each double bond, leading to possibilities like (2E,4E)-hexadiene, (2Z,4E)-hexadiene, (2E,4Z)-hexadiene, and (2Z,4Z)-hexadiene. These isomers will have different physical properties such as boiling points and melting points. Alkadienes like 2,4-hexadiene are often used as monomers in polymerization reactions to create various types of plastics and rubber. They can also participate in Diels-Alder reactions, a crucial type of cycloaddition reaction in organic synthesis. The specific properties and applications of 2,4-hexadiene are influenced by its isomeric form.
