Ans:
This is an example of an electrophilic aromatic substitution reaction. phenol generates phenoxide ion in alkaline medium, which is more electron-rich than phenol and thus more reactive to electrophilic attack. In this reaction, the electrophile is an aryldiazonium cation.
The faster the reaction, the stronger the electrophile.
The cation p-nitrophenyldiazonium is a stronger electrophile than the cation p-toluene diazonium.
As a result, it preferentially couples with phenol.

Invert sugar is another name for sucrose. Sugar beet sugar is a colourless, crystalline, and sweet substance made from sugar beets. It is very water soluble and has a dextrorotatory aqueous solution [α]D=+66.5? When cane sugar is hydrolyzed with dilute acids or the enzyme invertase, it creates an equimolar mixture of D− (+)− glucose and D− (−)− fructose. Sucrose is dextrorotatory as a result, and hydrolysis produces dextrorotatory glucose and laevorotatory fructose. Fructose's specific rotation is greater than that of glucose. As a result, the ensuing solut
