Answer:
Sandmeyer Reaction
Explanation:
When benzene diazonium chloride is treated with cuprous chloride in HCl, chlorobenzene is formed.
This reaction is called Sandmeyer reaction. In this reaction, the diazonium group is replaced by chloro group.
Sandmeyer reaction is used to replace the diazonium group with chlorine, bromine or cyano group.
Zn(NO3)2 + Cu will be the result of this single displacement (replacement) reaction :))
Might be false
Hope so
So sorry if it is wrong
The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.
The atmosphere has been divided into five layers based on the availability and the composition of different elements.
<h3>Troposphere</h3>
The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.
The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.
Thus, the presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
