Quizplus · Accepted Answer

Tertiary haloalkanes typically undergo elimination reactions due to the hindrance around the carbon bearing the halogen, making substitution reactions less favorable. E1 and E2 mechanisms are both common for tertiary haloalkanes. Addition reactions are unlikely due to the lack of a suitable nucleophile, and SS1 and SS2 substitution reactions are less likely due to the steric hindrance. Therefore, only options I and V can be eliminated, leaving options II, III, and IV. Among these, option D includes E1 and E2 mechanisms, which are the most likely for tertiary haloalkanes.
