What is isomerism in organic chemistry?

• Isomerism is the phenomenon where compounds have the same molecular formula but different structural arrangements.

• Isomerism refers to the ability of compounds to exist in multiple phases at different temperatures.

• Isomerism is the process of combining different compounds to form a new compound.

• Isomerism is the reaction of compounds with water to form alcohols.

Define organic chemistry.

• The study of inorganic compounds and their properties.

• The branch of chemistry that studies the structure, properties, composition, reactions, and synthesis of carbon-containing compounds.

• A field focused on the analysis of metals and their reactions.

• The examination of biological processes at the molecular level.

What is the IUPAC naming system?

• A systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry.

• A casual approach to naming chemical compounds based on their common names.

• A method used exclusively for naming inorganic compounds.

• A system that categorizes chemicals based on their physical properties.

What is the difference between alkanes and alkenes?

• Alkanes are unsaturated hydrocarbons with at least one double bond, while alkenes are saturated hydrocarbons with single bonds.

• Alkanes are saturated hydrocarbons with single bonds, while alkenes are unsaturated hydrocarbons with at least one double bond.

• Alkanes contain only carbon and hydrogen, while alkenes contain oxygen as well.

• Alkanes have a higher boiling point than alkenes due to their structure.
