Exploring Organic Chemistry Concepts

What is the basic unit of an organic compound?

• Hydrogen atom

• Oxygen molecule

• Carbon atom

• Nitrogen ion

Define hydrocarbons and give an example.

• Methane (CH4)

• Benzene (C6H6)

• Propane (C3H8)

• Ethanol (C2H5OH)

What is the difference between saturated and unsaturated hydrocarbons?

• Saturated hydrocarbons are liquid at room temperature; unsaturated hydrocarbons are solid.

• Saturated hydrocarbons contain only double bonds; unsaturated hydrocarbons contain single bonds.

• Saturated hydrocarbons have a higher boiling point than unsaturated hydrocarbons.

• Saturated hydrocarbons have only single bonds; unsaturated hydrocarbons have double or triple bonds.

Name the functional group present in alcohols.

• Amino group (-NH2)

• Hydroxyl group (-OH)

• Carboxyl group (-COOH)

• Carbonyl group (C=O)

What is the general formula for alkanes?

• CnH(2n+2)

• C(n-1)H(2n-1)

• CnH2n

• C2nHn+2

Explain what is meant by isomerism in organic chemistry.

• Isomerism is the process of combining two different compounds into one.

• Isomerism is the phenomenon where compounds have identical structures but different molecular weights.

• Isomerism is the existence of compounds with the same molecular formula but different structures or arrangements.

• Isomerism refers to compounds with different molecular formulas.

What type of reaction occurs when an alkene reacts with hydrogen?

• Oxidation

• Hydrolysis

• Dehydrogenation

• Hydrogenation

Identify the functional group in carboxylic acids.

• Amino group (-NH2)

• Carbonyl group (C=O)

• Hydroxyl group (-OH)

• Carboxyl group (-COOH)

What is a polymer? Give an example of a natural polymer.

• Chitin is a man-made polymer.

• Rubber is a type of metal.

• Starch is a synthetic polymer.

• An example of a natural polymer is cellulose.

Describe the significance of organic chemistry in everyday life.

• Organic chemistry has no impact on environmental issues.

• Organic chemistry is only relevant in industrial processes.

• Organic chemistry is significant in everyday life as it underpins the development of medicines, food, and materials, influencing health, nutrition, and technology.

• Organic chemistry is solely focused on studying inorganic compounds.
