Cu cannot liberate H2 from a solution of dilute HCl as hydrogen is above copper in the electrochemical series. E° H+/½H2 = ± 0.00 E° Cu2+ /Cu = +0.34

Q. Assertion: Copper liberates hydrogen from a solution of dilute hydrochloric acid.
Reason: Hydrogen is below copper in the electrochemical series.

If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion

If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion

If Assertion is true but the Reason is false

If both Assertion and Reason are false

Cu cannot liberate $H_{2}$ from a solution of dilute HCl as hydrogen is above copper in the electrochemical series.

$E_{H^{+} /½ H_{2}}^{\circ} = \pm 0.00$

$E_{C u^{2 +} / C u}^{\circ} = + 0.34$
