Chapter 21, Problem 38P

Interpretation Introduction

Interpretation:

The reasonable structures for the compounds A and B that results from the bromination of $\text{3-methyl-2-butanone}$ are to be represented.

Concept introduction:

Aldehydes and ketones contain carbonyl $\left(\text{C=O}\right)$ functional group in their parent chain. The halogenation of aldehyde or ketone takes place by the replacement of alpha proton to the carbonyl group by halogen.

Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations.

Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment around the hydrogen atom.
