For the alcohol reaction below. give the major organic product.

For each alcohol reaction below, give the major organic product. media/c7a/c7a9be07-31d0-4880-a357-d9

Answer

General guidance

Concepts and reason
The concept used to solve the first reaction is the conversion of alcohol to alkyl halide with HBr. This product occurs through mechanism. For the second reaction, the conversion of alcohol to alkyl halide with thionyl chloride, SOCI,. This product occurs through mechanism.

Fundamentals

reaction is a single step reaction. The rate of the reaction depends on both concentration of substrate and concentration of nucleophile. In reactions, rearrangement of carbocation takes place.

Step-by-step

Step 1 of 2

The mechanism is as follows: secondary carbocation
1,2-methyl shift

The major organic product is as follows:


The -OH group in the alcohol gets protonated and forms a good leaving group. Next the secondary carbocation is formed by expelling out the leaving group. Then the secondary carbocation is converted to more stable tertiary carbocation. Finally, the bromide ion attacks the more stable tertiary carbocation and forms 2-bromo-2,3-dimethylbutane.

Step 2 of 2

The major organic product is as follows:


The -OH group reacts with and forms an intermediate followed by the loss of proton with pyridine and generates a good nucleophile. Finally, the chloride ion attacks the carbon having leaving group and forms the desired compound. The formation of product occurs through mechanism.

Answer

The major organic product is as follows:

The major organic product is as follows:
