Chapter 13, Problem 13.12P
Interpretation Introduction

(a)

Interpretation:

The mole percent of the each given compound in the mixture is to be stated.

Concept introduction:

NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is known as a proton in the NMR spectroscopy.

The number of NMR signal in a compound is equal to the number of chemically non-equivalent protons present in that compound. The more the shielded proton lesser will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region or vice versa.

Interpretation Introduction

(b)

Interpretation:

Among 1 mole percent CH3I impurity in (CH3)3CBr, and 1 mole percent (CH3)3CBr impurity in CH3I, the one which is more easily detected by NMR is to be stated with an explanation.
