Question

Acetone reacts with water in presence of catalyst produces:

Options
  • A

    propan-2-ol

  • B

    propan-1,2-diol

  • C

    propan-2,2-diol

  • D

    propanol

Explanation

When acetone reacts with water in the presence of a catalyst, it undergoes hydration to produce propan-1,2-diol, also known as propylene glycol. This reaction involves the addition of a water molecule across the double bond of the carbonyl group in acetone, resulting in a compound with two hydroxyl groups. The other options are incorrect because propan-2-ol is not formed from this reaction; propan-2,2-diol is unrelated to the reaction of acetone with water; and 'propanol' is too vague, as it could refer to either isomer (propan-1-ol or propan-2-ol) that are not formed in this specific reaction.

This is an alcohol formed from the hydration of propene, not from the reaction of acetone with water.

This is the correct answer, as acetone reacts with water in the presence of a catalyst to form propan-1,2-diol, a diol compound.

This compound is a tertiary alcohol and does not result from the reaction of acetone with water.

This term generally refers to propan-1-ol or propan-2-ol; neither is the product of the reaction in question.
