Copper does not react with HCl to give H2 gas. why?

WebSep 15, 2008 · An ene reaction can be broadly classified as the reaction of an alkene bearing an allylic hydrogen (the ene) with a double or triple bond, known as the enophile. These reactions are accompanied by migration of the double bond and a 1,5-hydrogen shift. The reaction can be represented generically as shown in Scheme 1. WebThe reaction is: Zinc + Sulfuric acid → Zinc sulfate + Hydrogen. Zn (s) + H 2 SO 4 (aq) → ZnSO 4 (aq) + H 2 (g) In test tube 2, copper is the catalyst for the reaction, and the reaction should be faster than in test tube 1, but may not be as fast as test tube 3.

So, when copper is heated with conc. H2SO4, a redox reaction occurs and the acid gets reduced to sulphur dioxide.However, chloride ion has the lowest oxidation state, and the most concentrates hydrochloric acid is not very concentrated (around 37%) so the H+ cannot act as oxidizing agent.

WebCopper has higher reduction potential than hydrogen because of which copper will stay in reduced form, Cu, rather than oxidizing to Cu + or Cu 2+. Therefore, copper does not react with HCl to give H 2 gas. Thus the answer is (A) The reduction potential of copper is higher than hydrogen. Solve any question of Hydrogen with:-.
