Vedclass · Answer

(D) The correct answer is $(D)$.$Cu + HCl 	o 	ext{No reaction}$.Copper is less reactive than hydrogen in the electrochemical series,as indicated by its positive standard reduction potential $(E_{Cu}^{0} = +0.34 \ V)$ compared to hydrogen $(E_{H}^{0} = 0.00 \ V)$.Therefore,copper cannot displace hydrogen from dilute acids.
