because we need hydrogen as well as chlorine in that reaction
Cu ion being a Lewis acid stabilized the intermediate formed while Na ion can not.
The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts. It involves the substitution of a diazonium group (RN2+) with a halide ion. The Sandmeyer reaction is commonly used in organic chemistry for the preparation of various aromatic compounds.
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.
Iodine is commonly used in organic chemistry synthesis reactions as a halogenation agent to introduce iodine atoms into organic molecules. It can also be used in Sandmeyer reactions to convert aryl amines into aryl iodides. Additionally, iodine can be utilized in the synthesis of various pharmaceuticals and dyes.
The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts. It is named after the Swiss chemist Traugott Sandmeyer. An aromatic (or heterocyclic) amine quickly reacts with a nitrite to form an aryl diazonium salt, which decomposes in the presence of copper(I) salts, such as copper(I) chloride, to form the desired aryl halide. The reaction is a radical-nucleophilic aromatic substitution.
The Gatterman reaction is used to convert benzene to benzaldehyde (and derivatives). You need to use the Sandmeyer reaction to add iodo groups to aromatic rings. I think textbooks sometimes gets the two reactions mixed up.
First, its HCl, with a lowercase L, not HCI. The reaction is HCl + NaOH --> H2O + NaCl
NaCl doesn't undergo a chemical reaction with NaOH, so you wouldn't be able to tell.
Hydrochloric acid is used in a haloform reaction to provide the chloride ions needed for the reaction to take place. The chloride ions participate in the halogenation step of the reaction, leading to the formation of the haloform product.
Any problem, any reaction.
Sand Meyer Reaction is a chemical reaction that is used to prepare aryl halides from aryl diazonium salts. Check links in the left column. This is a very sophisticated question that would nail 99% of all Organic Chemistry teachers. Diazonium mechanisms vary with the nucleophile. When using Fluorine for example, the Sn1 occurs forming the VERY RARE aryl cation. In Sandmeyer reactions, we use Copper. The mechanism is a Non-Chain Free Radical substitution mechanism.We call this an Srn1 mechanism in Advanced Organic Chemistry. Dr Jim Romano CEO Orgoman.com and Romano Scientific New York
In the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl), the chemical compound that is used up is sodium hydroxide (NaOH), as it reacts with hydrochloric acid to form water (H2O) and sodium chloride (NaCl).
