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.

$$\underset{\mathrm{Alcohol}}{6(\mathrm{CH}{\phantom{A}}_3){\phantom{A}}_3\mathrm{C}-\mathrm{OH}}+\underset{\mathrm{Active}\mathrm{metal}}{2\mathrm{Al}}⟶\underset{\mathrm{Alkoxide}}{2[(\mathrm{CH}{\phantom{A}}_3){\phantom{A}}_3\mathrm{C}-\mathrm{O}]{\phantom{A}}_3\mathrm{Al}}+3\mathrm{H}{\phantom{A}}_2\uparrow$$

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