Vedclass · Answer

(B) Dehydrogenation of alcohols typically involves the removal of hydrogen to form a carbocation intermediate or carbonyl compound. Among the given options,$CH_3-C(CH_3)_2-OH$ is a tertiary $(3^{\circ})$ alcohol. Upon dehydration or related processes,it forms a tertiary carbocation,$(CH_3)_3C^+$,which is the most stable due to the $+I$ effect and hyperconjugation of nine $\alpha$-hydrogens.

Which of the following compounds gives the most stable carbocation upon dehydrogenation?
