JEE Main levelSingle correct optionDifficulty 2 of 3o2186

3-Methylbut-1-ene is treated with dilute $H X_{2} SO X_{4}$ in water. The major product is

A2-methylbutan-1-ol
B3-methylbutan-2-ol
C3-methylbutan-1-ol
D2-methylbutan-2-ol

Answer: D

Protonation gives a secondary cation, which rearranges by a 1,2-hydride shift to the tertiary cation. Water captures it to give 2-methylbutan-2-ol.
