Solution By Steps

Step 1: Determine the Reaction

The reaction involves the addition of water (H2O) to a molecule. This is known as hydration.

Step 2: Identify the Functional Group

The reactant likely contains a carbon-carbon double bond (alkene) since water is being added.

Step 3: Understand the Hydration Process

In the presence of an acid catalyst, water adds across the double bond to form an alcohol.

Step 4: Predict the Major Product

The major product of the hydration of an alkene with water is an alcohol. The hydrogen atom from water adds to one carbon of the double bond, and the hydroxyl group (-OH) adds to the other carbon.

Final Answer

The predicted major product of the reaction is an alcohol.

Key Concept

Hydration

Key Concept Explanation

Hydration is the addition of water to an unsaturated compound, often catalyzed by an acid, resulting in the formation of an alcohol. This process is commonly used in organic chemistry to synthesize alcohols from alkenes.
