The process of refining Nickel is called the Mond Process. It is also called the Carbonyl process and is one of the Nickel refining processes. Nickel usually comes in the form of Nickel oxide along with other impurities. A mixture of Hydrogen gas and Carbon monoxide gas is added to
When aniline treated with bromine water, the bromine water gets decolourized and white precipitate is formed. This reaction results in the formation of 2,4,6-tribromo phenylamine. This reaction is an example of bromination.
Hope this information helps you.

This reaction is called dehydration of alcohol and the products usually formed are alkene and water. The products will be CH3CH=CH3 +H2O .
To understand this you have to understand the Saytzeff rule - hydrogen is eliminated from that carbon atom which has less number of hydrogen atoms attached to
Hi,
