Which of the following is the correct definition of a homologous series?
A series of compounds with the same molecular mass
A series of compounds having identical physical properties
A series of compounds having different functional groups
A series of compounds having the same functional group and similar chemical properties
A series of compounds having the same functional group and similar chemical properties
A homologous series is defined by a common general formula, same functional group, and members differing by a CH2 unit.
A homologous series is defined by a common general formula, same functional group, and members differing by a CH2 unit.
Analyze the Terminology
A homologous series is a group of organic chemical compounds that possess the same functional group and similar chemical properties, with each successive member differing by a -CH2- unit.
Evaluate Options
Option D aligns perfectly with the chemical definition: sharing a common functional group leads to characteristic similar chemical reactions.
A: Incorrect because molecular mass increases as the chain lengthens. B: Incorrect because physical properties like boiling point change gradually with mass. C: Incorrect because members MUST share the same functional group.
D is correct because members of a homologous series share a common functional group and exhibit similar chemical properties.
Remember that physical properties (BP/MP) trend upward in a series due to increasing Van der Waals forces, while chemical properties remain constant due to the identical functional group.
