Classification of Organic Compounds

What is an organic compound?

• Any compound that is found in nature.

• A chemical compound that contains metals.

• A compound that contains only hydrogen and oxygen.

• An organic compound is a chemical compound that contains carbon.

Name the main types of organic compounds.

• Water, salts, metals, gases

• Sugars, starches, fibers, acids

• Vitamins, minerals, enzymes, hormones

• Carbohydrates, lipids, proteins, nucleic acids

What is the functional group of alcohols?

• -NH2 (amino group)

• -CHO (aldehyde group)

• -OH (hydroxyl group)

• -COOH (carboxyl group)

How do alkanes differ from alkenes?

• Alkanes are always gases, while alkenes are always liquids.

• Alkanes contain more carbon atoms than alkenes.

• Alkanes have only single bonds; alkenes have at least one double bond.

• Alkenes have only single bonds; alkanes have at least one double bond.

What is the general formula for alkenes?

• CnH2n+1

• CnH2n

• CnH2n-1

• C2nH2n-2

Define isomerism in organic chemistry.

• Isomerism is the process of combining different compounds into a single structure.

• Isomerism refers to compounds with different molecular formulas but similar structures.

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

• Isomerism is the existence of compounds with the same structure but different molecular weights.

What are the characteristics of aromatic compounds?

• Aromatic compounds are cyclic, planar, have conjugated pi electrons, follow Hückel's rule, and are stable due to resonance.

• Aromatic compounds do not have any pi electrons.

• Aromatic compounds are always linear and non-planar.

• Aromatic compounds are unstable and do not follow Hückel's rule.

Explain the significance of functional groups in organic compounds.

• Functional groups have no impact on organic compounds.

• Functional groups are crucial in determining the chemical properties and reactivity of organic compounds.

• Functional groups are irrelevant in organic chemistry.

• Functional groups only affect the physical state of compounds.

What is the difference between saturated and unsaturated hydrocarbons?

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

• Saturated hydrocarbons are more reactive than unsaturated hydrocarbons.

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

• Unsaturated hydrocarbons have only single bonds; saturated hydrocarbons have no bonds.

Give an example of a polymer and its monomer.

• Polystyrene and glucose

• Nylon and amino acids

• Polyethylene (polymer) and ethylene (monomer)

• PVC and propylene
