Question

Predict the products when 1-propanol is heated in the presence of an acid? There are two products. I have one of them 1-propene, what is the second product?

Answer 1

Concepts and reason

Alcohols undergoes dehydration at high temperatures in the presence of acid to form alkenes.

Fundamentals

Dehydration of alcohols to form alkenes is a dehydration reaction. The primary, secondary, and tertiary alcohols require different temperature ranges for dehydration. Alcohols act as both acids and base depending on the reaction conditions. The oxygen in the -OH group acts as a base by donating the electron pair to an electron deficient species.

The structure of 1-propanol is as follows:

First, the alcoholic group gets protonated as follows:

The products of the reaction are as follows:

Ans:

The products of the reaction are as follows:
