What happens when cyclohexanone reacts with isopropyl alcohol in the presence of aluminium isopropoxide?

Cyclohexanol + Acetone 

The correct answer is option 1. Cyclohexanol + Acetone.

When cyclohexanone reacts with isopropyl alcohol in the presence of aluminum isopropoxide, the reaction is an example of the Meerwein-Ponndorf-Verley (MPV) reduction. This reaction specifically reduces ketones to secondary alcohols using an aluminum alkoxide catalyst and isopropyl alcohol as the reducing agent.

In this reaction:

Cyclohexanone (a ketone) is reduced to cyclohexanol (a secondary alcohol). Isopropyl alcohol (the reducing agent) is oxidized to acetone.

So the products of the reaction are cyclohexanol and acetone.

Thus, the correct option is: 1. Cyclohexanol + Acetone
