Answer 1

Answer:

. Assertion: Copper does not reacts with the H2SO4

Reason: Copper is more reactive than hydrogen

(a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion

(b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion

(c) Assertion is true but the Reason is false

(d) "The statement of the Assertion is false but the Reason is true

Answer 2

The correct option for this question is option c: Assertion is true but the Reason is false.

• Copper has lesser reactivity in its elemental form than hydrogen in its elemental state or in compounds when it has the oxidation state +1.
• In terms of reactivity series, copper is less reactive than hydrogen.
• The elements above a specific element are more reactive, whereas the elements below it are less reactive.
• The assumption is correct because copper cannot displace hydrogen in dilute sulphuric acid (oxidation state: +1).
• The reasoning is wrong since copper cannot displace, implying copper is less reactive than hydrogen.
• Hence, option c is accurate in this case.
