Question

Assertion : Copper reacts with hydrochloric acid and liberates hydrogen from the solution of dilute hydrochloric acid.

Reason : Hydrogen is present below copper in the electrochemical series.

• A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
• C. If assertion is true but reason is false.
• D. If the assertion and reason both are false.

Answer 1

The correct option is D If the assertion and reason both are false.

Copper is present below hydrogen therefore hydrogen from HCl cannot be liberated by treating with copper. Hence assertion and reason both are false.
