Question

Which of the following statements is wrong for a homologous series?

• A. All members have the same general formula
• B. All members have the same functional group
• C. All members have the same chemical properties
• D. All members have the same physical properties.

Answer 1

The correct option is D All members have the same physical properties.

A series of organic compoiunds that have similar structural feautres but differ from adjacent members by $(-C{H}_2)$ group are referred to as homologous series.
They have same general formula and because of a same functional group, they have similar chemical properties but due to varying mass, they have different physical properties.
