Two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below:Assertion (A): Following are the members of a homologous series: CH3OH, CH3CH2OH, CH3CH2CH2OHReason (R): A series of compounds with same functional group but differing by – CH2– unit is called a homologous series.(a) Both (A) and (R) are true and (R) is correct explanation of the assertion.(b) Both (A) and (R) are true but (R) is not the correct explanation of the assertion.(c) (A) is true but (R) is false.(d) (A) is false but (R) is true.
Correct Answer: (a) Both (A) and (R) are true and (R) is correct explanation of the assertion.
Explanation: A series of compounds with the same functional group but differing by – CH2– unit is called a homologous series. Example: Following are the members of a homologous series: CH3OH, CH3CH2OH, CH3CH2CH2OH.
