(i) Assertion: If a solution contains both $\text{H}^+$ and $\text{Na}^+$ ions, the $\text{H}^+$ ions are reduced first at cathode. Reason: Cations with higher $E^\circ$ value are reduced first at cathode. (a) Both Assertion and Reason are true, and Reason is the correct explanation for Assertion. (b) Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion. (c) Assertion is true but Reason is false. (d) Assertion is false but Reason is true. (ii) Assertion: Addition of bromine water to 1-butene gives two optical isomers. Reason: The product formed contains two asymmetric carbon atoms. (a) Both Assertion and Reason are true, and Reason is the correct explanation for Assertion. (b) Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion. (c) Assertion is true but Reason is false. (d) Assertion is false but Reason is true.
