Interpretation Introduction

Interpretation:

The number of acetonide groups present in the given compound based on the 13C NMR spectrum is to be determined.

Concept introduction:

The acetonides are a group of cyclic acetals that act as a protective group for vicinal-cis -OH groups of carbohydrates. It can be removed by the hydrolysis of ketal.

The 13C NMR or the carbon-13 nuclear magnetic resonance is an analytical technique in chemistry to know the carbon atoms in the structure of a compound. It is an important tool in structure elucidation of organic compounds. It can detect the only C13 isotopes and not C12 as the latter has zero net spins.
