Chapter 13.9, Problem 13.15P

(a)

Interpretation Introduction

Interpretation:

The chemical shifts of each type of proton are to be determined.

Concept introduction:

The chemical shift is defined as the difference in parts per million in the absorption spectrum of a particular proton from the absorption position of a reference proton. Tetramethylsilane is taken as the reference proton. Chemical shifts are measured in parts per million, and it is dimensionless quantity.

(b)

Interpretation Introduction

Interpretation:

The number of NMR peaks for each type of proton is to be determined.

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 called as a proton in the NMR spectroscopy.

(c)

Interpretation Introduction

Interpretation:

The tree to show the splitting predicted for the absorption of the circled proton is to be drawn.

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 called as a proton in the NMR spectroscopy.
