Chapter 20.5, Problem 20.13P

Interpretation Introduction

Interpretation:

The acetals in sucralose should be located and each alkyl halide should be labeled as 1⁰, 2⁰ or 3⁰

Concept Introduction:

Addition of one molecule of alcohol to an aldehyde or ketone results in a hemiacetal. Here, the C=O double bond breaks and single bonds are formed. If the hemiacetal is acyclic, it is not stable. Acyclic hemiacetal reacts with a second alcohol molecule and forms acetal.

likewise, a disaccharide is formed when a hemiacetal of a one monosaccharide is reacted with a hydroxyl group of a second monosaccharide forming an acetal.

Primary alkyl halide are halides that have one alkyl group bonded to the same carbon as the halide. Likewise, secondary and tertiary halides are halides that have two and three alkyl groups bonded to same carbon as halide respectively.
