Interpretation Introduction

Interpretation:

The stereochemical outcome of radical bromination for the given compound should be identified.

Concept introduction:

Radical bromination: It is a type of halogenation reaction in which the bromine atom gets bonded with the alkane or alkyl substituents resulting to the product with added bromine atom via radical mechanism.

Radical reaction of $B{r}_2$ is radical substitution of alkane and generates the alkyl halide and hydrogen iodide.

Stability of Radicals: Radicals are highly unstable due to its unpaired valence electron of an atom.

The increasing order of radical stability is given below

Benzylic > allylic > tertiary > secondary > primary > methyl

Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.

Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.

Enantiomers: They are chiral molecules whose mirror images are not superimposable.

Diastereomers: The molecules that are not mirror images and not superimposable of each other.

Chiral carbon: Carbon is considered to be chiral if all the four substituents bonded with that carbon are different.
