When we discuss the chemical reactions of alkenes, we will see that the primary site of reaction is the double bond and the most common type of reaction is the addition of atoms to the double bond to make a saturated molecule. The reaction is often done in a mix of organic solvent and water using n. The increase in stability of 2,4hexadiene over 1,3hexadiene both are conjugated is due to the increased double bond substitution of the former, a factor noted earlier for simple alkenes.
