(a)

Interpretation Introduction

Interpretation:

The structure of phenylalanine as it exists in D2O solution is to be stated.

Concept introduction:

The peaks in NMR spectrum are due to hydrogen atoms. Different signals are produced from different neighboring substituents of hydrogen atoms. Information about the structure of a compound is obtained by chemical shifts. Peaks due to aromatic protons occur between 78ppm.

(b)

Interpretation Introduction

Interpretation:

The peaks in the spectrum are to be assigned to the protons in the structure.

Concept introduction:

The peaks in NMR spectrum are due to hydrogen atoms. Different signals are produced from different neighboring substituents of hydrogen atoms. Information about the structure of a compound is obtained by chemical shifts. Peaks due to aromatic protons occur between 78ppm.

(c)

Interpretation Introduction

Interpretation:

The reason for the absence of NH2 or COOH protons in the spectrum is to be stated.

Concept introduction:

The peaks in NMR spectrum are due to hydrogen atoms. Different signals are produced from different neighboring substituents of hydrogen atoms. Information about the structure of a compound is obtained by chemical shifts. Peaks due to aromatic protons occur between 78ppm.

(d)

Interpretation Introduction

Interpretation:

The relationship between the two protons that generate nearly mirror-image multiplets at 3.1 and 3.3 is to be stated.

Concept introduction:

The peaks in NMR spectrum are due to hydrogen atoms. Different signals are produced from different neighbouring substituents of hydrogen atoms. Information about the structure of a compound is obtained by chemical shifts. Peaks due to aromatic protons occur between 78ppm.
