Concept explainers

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…

lonone
The aroma of violets is due to ionone.

a. What functional groups are present in ionone?
b. Is the double bond on the side chain ds or trans?
c. What are the molecular formula and molar mass of ionone?
d. How many moles are in 2.00 mL of ionone?
e. When lonone reacts with hydrogen in the presence of a platinum catalyst, hydrogen adds to the double bonds and converts the ketone group to an alcohol. Draw the condensed structural formula and give the molecular formula for the product.
f. How many milliliters of hydrogen gas at STP are needed to completely react with 5.0 mL of ionone?
