Chapter 22, Problem 42P

Interpretation Introduction

Interpretation:

The structure of the given compound is to be determined, based on the ${}^{13}\text{CNMR}$ spectrum.

Concept introduction:

Alditols are the sugar alcohols formed by the addition of hydrogen to a monosaccharide. The reduction of aldoses or ketoses through sodium borohydride (${\text{NaBH}}_{\text{4}}$) results in the formation of alditols.

The ${}^{13}\text{CNMR}$ or the carbon-13 nuclear magnetic resonance is an analytical technique in chemistry used to know the carbon atoms present in the structure of a compound. It is an important tool in structure elucidation of organic compounds. It can detect the only ${\text{C}}^{13}$ isotopes and not ${\text{C}}^{12}$ as the latter has zero net spins.
