Vedclass · Answer

(D) Step $1$: Dehydration of $2-methylpropan-2-ol$ with $20\% H_2SO_4$ at $363 \ K$ gives $2-methylprop-1-ene$ $(A)$ as the major product via $E1$ mechanism.$(CH_3)_3C-OH \xrightarrow{H^+} (CH_3)_3C^+ \xrightarrow{-H^+} CH_2=C(CH_3)_2$ $(A)$.Step $2$: Acid-catalyzed hydration of $2-methylprop-1-ene$ $(A)$ follows Markovnikov's rule to give $2-methylpropan-2-ol$ $(B)$ as the major product.$CH_2=C(CH_3)_2 + H_2O \xrightarrow{H^+} (CH_3)_3C-OH$ $(B)$.Thus, the product '$B$' is $tert-Butyl alcohol$.

Identify product '$B$' in the following series of reactions: $2-methylpropan-2-ol \xrightarrow{20\% H_2SO_4, 363 K} A \xrightarrow{H_2O, \Delta, Conc. H_2SO_4} B$
