Understanding Homologous Series

Front

What is a homologous series?

Back

A homologous series is a group of organic compounds that have the same functional group and similar chemical properties, with each successive member differing by a -CH2- unit.

Front

How can you identify a homologous series from a molecular formula?

Back

A homologous series can be identified by a consistent difference in molecular formulas, usually by -CH2- units.

Front

What is the significance of functional groups in homologous series?

Back

Functional groups define the chemical behavior and properties of compounds in a homologous series.

Front

How do physical properties change in a homologous series?

Back

Physical properties such as boiling point and melting point increase with the number of carbon atoms.

Front

What are alkanes?

Back

Alkanes are saturated hydrocarbons that contain only single bonds between carbon atoms.

Front

What are alkenes?

Back

Alkenes are unsaturated hydrocarbons that contain at least one double bond between carbon atoms.

Front

What are alkynes?

Back

Alkynes are unsaturated hydrocarbons that contain at least one triple bond between carbon atoms.

Front

What is the general formula for alkanes?

Back

The general formula for alkanes is CnH2n+2.

Front

What is the general formula for alkenes?

Back

The general formula for alkenes is CnH2n.
