when 3-methylbutan-2-ol is treated with HBr, the following reaction takes place:

Give the mechanism of this reaction.
Hint : The secondary carbocation formed in step II rearranges to a more stable tetriary carbocation by a hydride ion shift form the third carbon atom.

When 3-methylbutan-2-ol is treated with HBr,the, following reaction takes place: Give a mechanism for this reaction. (Hint: The secondary carbocation formed in step If, the arranges to a more stable- tertiary carbocation by a hydride ion shift from 3rd carbon atom.)

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.

When 2-bromo-3-methylbutane is treated with aqueous KOH, it follows S_(N)-1 mechanism. The product formed is :

Assertion : When 2, 3-dimethyl butane-2, 3-diol is treated with dil. H_(2)SO_(4) , the major product is pinacolone. Reason : The reaction proceeds via carbocation intermediate and its rearrangement.
