WebJul 1, 2024 · Study Notes. The two alkenes, cis-CH 3 CH=CHCH 3 and (CH 3) 2 C=CH 2 have similar heats of hydrogenation (−120 kJ/mol and −119 kJ/mol, respectively), and are therefore of similar stability. However, they are both less stable than trans-CH 3 CH=CHCH 3 (−116 kJ/mol).. You may wonder why an sp 2-sp 3 bond is stronger than an sp 3-sp 3 …
