3-Methylbut-1-ene is treated with $BH X_{3} \cdot THF$ and then $H X_{2} O X_{2} / NaOH$ . The major product is

No carbocation forms in hydroboration, so there is no rearrangement. Boron adds to the terminal carbon and oxidation gives

(CH X_{3}) X_{2} CHCH X_{2} CH X_{2} OH

, 3-methylbutan-1-ol.
