Question

Assertion (A): When sulphuric acid reacts with copper, it produces hydrogen gas.

Reason (R): Copper is more reactive than hydrogen in the reactivity series.

पर्याय

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If both A and R are false.

Explanation:

The assertion is false because copper does not react with dilute sulfuric acid to produce hydrogen gas. The reason is also entirely false because copper is placed below hydrogen in the metal reactivity series, meaning it is less reactive than hydrogen and cannot displace it.
