An alloy of Zn and Cu is dissolved in dil. HC1. Hydrogen gas is evolved. In this evolution of gas (a) only zinc reacts with dil. HC1 (b) only copper reacts with dil. HC1 (c) both zinc and copper react with dil. HC1 (d) only copper reacts with water
Option A. Copper (Cu) lies below Hydrogen and therefore it cannot reacts with Hydrogen while Zinc (Zn) lies above the Hydrogen in the table and thus it reacts with HCl to liberate the Hydrogen gas
