When 3-methylbutan-2-ol is treated with HBr, the following reaction takes place:   `CH_(3)-underset(CH_(3))underset("|  ")("C ")H-underset(OH)underset("| ")("C")H-CH_(3)overset(HBr)rarr CH_(3)-overset(Br)overset("| ")underset(CH_(3))underset("|  ")("C ")-CH_(2)-CH_(3)`  Give a mechanism for this reaction.  (Hint : The secondary carbocation formed in step II rearranges to a more stable tertiary carbocation by a hydride ion shift from 3rd carbon atom.
