How can propan-2-one be converted into tert- butyl alcohol?

Propan-2-one can be converted into tert- butyl alcohol by using Grignard reagent.

Propan-2-one is treated with CH₃MgBr in the presence of dry ether (Grignard reagent), followed by the hydrolysis to yield tert- butyl alcohol.

• The chemical reaction involved is:

Arrange the following compounds in decreasing order of acidity.

H₂O, ROH, HC ≡ CH
