The Heat of Hydrogenation (HOH) of an alkene with a constant number of bonds is inversely proportion — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Maximum stability = Minimum HOH. Stability is dictated by $\alpha$ -hydrogens. 1-Pentene (2 $\alpha$ -H), 2-Methyl-1-butene (5 $\alpha$ -H), 3-Methyl-1-butene (1 $\alpha$ -H), 2-Methyl-2-butene (9 $\alpha$ -H). The highly substituted 2-Methyl-2-butene is the most stable and releases the least heat.
