Answer 1

The correct answer is Different number of carbon atoms but contain the different functional group

Key Points

Option 3 correctly identifies that a homologous series is a series of carbon compounds that has different numbers of carbon atoms but contain the same functional group.
A homologous series is characterized by a general formula, and each successive member differs by a CH₂ unit.
Examples include alkanes (C_nH_2n+2), alkenes (C_nH_2n), and alkynes (C_nH_2n-2).
Members of a homologous series exhibit similar chemical properties and a gradual change in physical properties.

Additional Information

The concept of homologous series is essential in organic chemistry for understanding the behavior and properties of organic compounds.
Functional groups are specific groups of atoms within molecules that have characteristic properties and determine the chemical behavior of the molecule.
The physical properties such as boiling points, melting points, and densities of the compounds in a homologous series typically show a regular pattern.
Understanding homologous series helps in predicting the properties of unknown compounds based on their position in the series.
