Interpretation Introduction

Interpretation:

The product of the reaction has to be predicted.

Concept interpretation:

Carbocation: carbon atom bears positive charged species with three bonds is called Carbocation and it plays vital intermediate in organic synthesis. Carbocation migratory aptitude is mainly depends on the stability of the carbocation. This type of carbocation undergoes inter or intra molecule reactions and it form more stable product this type of rearrangement called carbocation rearrangement.

Carbocation’s are classified in to three types as primary, secondary and tertiary depending on the number of carbon atoms which is attached to the ionized carbon.

Tertiary carbocation is more stable than secondary carbocation, secondary carbocation is more stable than the primary carbocation as shown below.

Hydration:

When alkene is undergoes hydration with water in the presence of sulfuric acid which yields the alcohol. In this reaction, the water molecule will behave like a hydrogen halide to the alkene which gives the addition product this reaction is known as a hydration reaction.

Organic Chemistry, Loose-leaf Version, Chapter 6, Problem 6.17P , additional homework tip  2

Alkene is reaction with water in the presence of sulfuric acid, first step is proton (H+) addition to the double bond which forms carbocation (more stable carbocation) followed by addition of hydroxide ion (-OH) yields alcohol as a product. The stability of carbocation is given below, Tertiary carbocation is more stable than the secondary, secondary carbocation is more stable than primary.

In hydration reaction, sulfuric acid is act as a proton donor, which is the driving force of the reaction. Hydration reaction will not go without acid (sulfuric acid).

Explanation of Solution

2-Butene reacts with water in the presence of sulfuric acid, first step is proton (H+) addition to the double bond which forms carbocation (more stable carbocation) followed by addition of hydroxide ion (-OH) yields alcohol as a product A. The reaction is shown below,
