Question

The number of moles of hydrogen gas formed when 2 moles of 2-methylpropan-2-ol reacts with aluminium is ____________.

Options

• 1

• 2

• 3

• 6

Answer 1

The number of moles of hydrogen gas formed when 2 moles of 2-methylpropan-2-ol reacts with aluminium is 1.

Explanation:

Alcohols react with active metals to form hydrogen gas.

\[\ce{\underset{Alcohol}{6(CH3)3C - OH} + \underset{Active metal}{2Al} -> \underset{Alkoxide}{2[(CH3)3C - O]3Al} + 3H2 ^}\]

∴ 2 moles of 2-methylpropan-2-ol will give one mole of hydrogen gas.
