Below Mechanism shows the mechanism of formation of diazonium ion. Aniline is treated with
Nitrosonium ion which is generated
in situ by the reaction of Sodium nitrile and strong acid. The resulting <span>
benzenediazonium ion on reaction with CuBr yields
Bromobenzene and on treatment with CuCN gives
Benzonitrile. Mechanism is as folow,</span>
Answer:
As the pressure decreases, the amount of oxygen available to breathe also decreases. Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather.
