Which of the following factors characterize members of the same homologous series?
-
A.
The chemical property change gradually throughout the series -
B.
physical properties of members are similar -
C.
They have the same molecular formular -
D.
Successive members undergo changes in molecular formula by (CH_{2})
Correct Answer: Option D
Explanation
The difference between every successive member of the same homologous series is always (CH_{2}) eg methane is (CH_{4}) and ethane is (C_{2}H_{6}), difference being (CH_{2}).
