                  For Assertion& Reason question follow the following directions.

             DIRECTION:   Each of these questions contains an Assertion followed by Reason.
             Read them carefully and answer the question on the basis of following options. You
             have to select the one that best describes the two statements.
             (a) If both Assertion and Reason are correct and Reason is the correct explanation of
             Assertion.

             (b) If both Assertion and Reason are correct, but Reason is not the correct
             explanation of Assertion.

             (c) If Assertion is correct but Reason is incorrect.
             (d) If Assertion is incorrect but Reason is correct.

             (e) If Assertion & Reason both are incorrect.

             Q.4    Assertion: The formula of ethanol is C 2H 5OH & ethanal is C 2H 5CHO.
                    Reason : The functional group of alcohol is -OH & for aldehyde it is -CHO
