Recall that Zaitsev’s rule says that more substituted alkenes are more stable. Therefore, propene is less stable than trans-but-2-ene, which is less stable than 2-methylbut-2- ene, which is less stable than 2,3-dimethylbut-2-ene. In Chapter 7, we showed that we could demonstrate this stability ordering by using heats of hydrogenation. a) Does the same apply for other groups, besides alkyl groups? For example, compare the stability of propene, trans-but-2-ene and trans-1-chloroprop-1-ene to compare the effects of adding a chlorine instead of...
