Inorganic Chemistry and the Periodic Table The reactivity increases down the group as the atomic radii increase there is more shielding. 6 Areas outside the box will not be scanned for marking 4 Group 2 metals and their compounds are used commercially in a variety of processes and applications. Metals have less electrons in their outer shell compared to non-metals and hence in reactions they give away their outermost electrons to … The disproportionation of chlorine with water is below: Cl 2 + H 2 O ⇌ \, \rightleftharpoons \, ⇌ HClO + HCl A disproportionation reaction is a reaction in which the same species is both oxidised and reduced; The reaction of chlorine with dilute alkali is an example of a disproportionation reaction; In these reactions, the chlorine gets oxidised and reduced at the same … Learn vocabulary, terms, and more with flashcards, games, and other study tools. %PDF-1.4 In group 7, the reactivity. %���� The general equation for the Group is: \[ 3X_{(s)} + N_{2(g)} \rightarrow X_3N_{2… The products of the reactions are chlorides. ... Hydrogen atoms are replaced in the methyl group by a chlorine atom, all the three hydrogen atoms in the methyl group are replaced by a chlorine atom. The group 2 metals will react with chlorine Mg + Cl2MgCl2 4. There is a diagonal relationship between lithium and magnesium. The Reactions of the elements with Chlorine. As you progress down the group:- Atomic radius increases, therefore there is more electron shielding.-. HOCl(aq) + HCl(aq) → Cl 2 (g) + H 2 O(l) When chlorine dissolves in water, it reacts to form the strong acid, HCl, and the weak but strongly oxidising acid, HOCl, which is responsible for the bleaching properties. {Throughout this section, explanations of redox reactions should emphasise electron transfer and oxidation number changes and include full and ionic equations (see also 2.1.5 Redox).} These can neutralise acids to form a salt and water.
