Question

Draw the structure of the major monohalo product for each of the following reactions:

Hint:

In the presence of heat, bromination occurs at the benzylic position, replacing a hydrogen atom with a bromine atom.

Answer 1

The reaction involves a bromination in the presence of heat, which typically leads to the formation of a benzylic bromination product. In this case, the hydrogen at the benzylic position (the carbon adjacent to the benzene ring) will be replaced by a bromine atom, forming 1-bromo-2-phenylethane as the major product.
The structure of the product is: \[ \text{C}_6\text{H}_5\text{CH}_2\text{CH}_2\text{Br} \]
