Lipids
The heterogeneous classes of organic compounds that are not water-soluble but are dissolved in organic solvents that are non-polar in nature are termed lipids. They are a long chain of fatty acids and esters of alcohols. Lipids are generally seen in seve…
Glycerophospholipid
Glycerophospholipid is the most abundantly occuring phospholipids found in the biological membranes. Lipids include a group of organic compounds like fats, hormones, oils, waxes, vitamins etc. They are non-polar molecules and are insoluble in water. Lipi…
Structure Of Camphor
A terpene with the molecular formula of C10H16O is a waxy, white color solid known as camphor. It is flammable. It also possesses a very pungent taste and a strong odor. There are various sources for extracting camphor from natural products such as the …
Glycolipid In Organic Chemistry
Glycolipids are lipids that are an important class of organic compounds in chemistry that have simple to complex applications. They contain carbohydrates, fatty acids, sphingolipids or a glycerol group. In other words, they are the modifications of lipid…
Diterpenoid
The terpenoid class includes diterpenoids, which are chemical compounds with 20 carbon atoms. They are made up of four isoprene units and are derived from geranylgeraniol, a C20 precursor. They have a C20H32 basic structure. These characteristics disting…

Chapter 15, Problem 15.94EP

(a)

Interpretation Introduction

Interpretation:

The hemiacetal carbon atom in the given structure has to be identified.

Concept Introduction:

Aldehydes contain a carbonyl group that is bonded to a hydrogen atom and a carbon atom.  Ketones are compounds that contain a carbonyl group bonded to two carbon atoms.  Aldehydes and ketones undergo addition reaction across the carbonyl group.

Aldehydes and ketones react with alcohol to form hemiacetal as the product.  This reacts with further molecule of aldehyde or ketone to form acetal.

Hemiacetal is a addition product that is obtained by reaction between aldehyde or ketone with alcohol.  The general reaction of hemiacetal formation can be given as,

General, Organic, and Biological Chemistry, Chapter 15, Problem 15.94EP , additional homework tip 1

From the above general structure of hemiacetal it is found that it is an organic compound that contains a carbon atom that is bonded to an alkoxy group and a hydroxyl group.

General, Organic, and Biological Chemistry, Chapter 15, Problem 15.94EP , additional homework tip 2

The carbon atom that contains both alkoxy group and the hydroxyl group is the hemiacetal carbon atom.
