Text Solution

Verified by Experts

The correct Answer is:
B

• Lecithin is a phospholipid found in cell membrane.
• Glycerol has 3 carbons, each bearing a hydroxyl (-OH) group.
• Lipids having only single bonds are called saturated fatty acids and lipids having one or more C=C double bonds are called unsaturated fatty acids.
• Palmitic acid has 16 carbon atoms including carboxyl carbon.
• Arachidonic acid has 20 carbon atoms including the carboxyl carbon.

Carbon forms a large number of compounds because of its two unique properties formed many have long straight chains of carbon, branched chains of carbon or rings of carbon. In these compounds, carbon atoms may form single, double or triple covalent bonds. Compounds in which the carbon atoms are linked to each other by single bonds are called saturated carbon compounds whereas compounds having at least one carbon-carbon double or triple bond are called unsaturated carbon compounds. Compounds containing only carbon and hydrogen are known as hydrocarbons. Based on the above information, answer the following questions. Give two examples of carbon compounds which have ring structure.
