Complete the following reaction: Ar - NH 2 → ? Ar - N 2 ⊕ Cl ⊝ → Cupprous chloride HCl ?

Aromatic primary amines react with nitrous acid to form diazonium salt. The chemical reaction is as follows: Benzene diazonium chloride reacts with cuprous chloride and hydrochloric acid to form chloro -benzene chloride and nitrogen, this reaction is known as the Sandmeyer reaction. The complete chemical reaction is as follows: Ar - NH 2 → NaNO 2 + HCl HNO 2 Ar - N 2 ⊕ Cl ⊝ → Cupprous chloride HCl Ar - Cl + N 2 .

Complete the following reaction: Ar - N 2 ⊕ Cl ⊝ → H 3 PO 2 ?

Benzene diazonium chloride when reacts with hypophosphorous acid which is a reducing agent the salt reduced to produce benzene. The complete chemical reaction is as follows: Ar - N 2 Cl + H 3 PO 2 + H 2 O ⟶ Ar — H + H 3 PO 3 + HCl + N 2 The diazonium is replaced by a hydrogen atom, that is, benzene would be formed. H 3 PO 2 gets oxidised H 3 PO 3 and Benzene diazonium chloride gets reduced to benzene.
