In which of the reaction formation of diazonium salts takes place?

In which of the reaction formation of diazonium salts takes place?

The electrophilic nitrosonium cation then nitrosates the nitrogen of the nucleophilic amine. After a series of protonic shifts, followed by loss of water, leads to the formation of diazonium salt.

When diazonium salt solution is treated with KI it forms?

When diazonium salt solution is treated with KI it introduces −I group in benzene ring to form Iodobenzene as a major product.

What is the mechanism of Finkelstein reaction?

The mechanism of the Finkelstein reaction is single-step S_{N}2 reaction with stereochemistry inversion. The classic Finkelstein reaction involves the process of an alkyl bromide or an alkyl chloride into an alkyl iodide which is treated with a sodium iodide solution in acetone.

Which one of the following Cannot be prepared by Wurtz reaction?

The Wurtz reaction cannot prepare methane because it contains only one carbon atom.

Which of the following are intermediates in Sandmeyer reaction?

Diazonium salt is intermediate in Sandmeyer’s reaction.

What is meant by diazonium salt?

Diazonium salts are a group of organic compounds that share one common R-N + 2X group of functions. R is an organic group, in R-N + 2X. For example, the group alkyl or aryl. And azo compounds may also be formed by reacting with other aromatic compounds by diazonium salts.

What happens when iodine and phosphorus and comes in contact with each other?

Answer. White phosphorus, P4, reacts with iodine, I2, in carbon disulphide (CS2) to form phosphorus(II) iodide, P2I4. The same compound is formed in the reaction between red phosphorus and iodine, I2, at 180°C.

Does iodine react with alkanes?

The reaction between alkanes and iodine: Iodine does not react with the alkanes to any extent – at least, under normal lab conditions. The reactions between alkanes and chlorine or bromine: There is no reaction in the dark.
