Cu ion being a Lewis acid stabilized the intermediate formed while Na ion can not.
Some common reagents used in Sandmeyer's reaction include sodium nitrite (NaNO2), cuprous chloride (CuCl), and hydrochloric acid (HCl). These reagents are typically used to convert aryl diazonium salts to various functional groups such as halides, cyanides, and hydroxyl groups.
Displacement reaction
When heated, CuCl2 decomposes into copper(I) chloride (CuCl) and chlorine gas (Cl2). This decomposition reaction is reversible, and the decomposition temperature varies depending on the specific conditions.
The cation in CuCl is copper (Cu+).
The theoretical yield of CuCl can be calculated using the stoichiometry of the reaction it is produced in. For example, if CuCl is produced from the reaction of Cu with HCl, the balanced chemical equation can be used to determine the amount of CuCl that can be produced. Theoretical yield is the maximum amount of product that can be obtained under ideal conditions.
Copper(I) chloride is the correct name for CuCl.
In CuCl, copper is typically found in its +1 oxidation state, while chlorine has a -1 charge. Therefore, the overall charge on CuCl is 0.
Copper Chloride
CuCl (copper(I) chloride) can be dissolved in water to form an aqueous solution, but it has limited solubility. When CuCl is added to water, it does not fully dissociate, resulting in a partially saturated solution. Therefore, while CuCl can exist in an aqueous form, it does not completely dissolve like more soluble salts.
When copper reacts with chlorine, copper chloride is formed. The balanced chemical equation for the reaction is: 2 Cu + Cl₂ → 2 CuCl
Yes, a reaction occurs between hydrochloric acid (HCl) and copper (Cu). The HCl will react with the copper to form copper chloride (CuCl2) and hydrogen gas (H2). This reaction is a classic example of a single replacement reaction.
In CuCl, copper is in +1 oxidation state, So that is a d10 system and the d-orbitals are completely filled. Hence colourless.
