Chemistry

The following depicts a chemical reaction leading to a Major Product Y.
Mercury has low boiling point so is refined by distillation method.
Copper refining is done through electrolytic refining.
Silicon is refined by zone refining method.
Nickel is refined by vapour phase refining.

Please consider the following Image

During nitration of aniline, meta- nitroaniline is also formed as product due to formation of –NH? group. The percentage of p, m and o product is 51%, 47% and 2% respectively

In Hoffmann bromamide reaction, hypobromite ion react with amide and in this reaction carbonyl group is lost as CO? ²? in form of Na? CO?

Deficiency of vitamin K causes increase in blood clotting time.

CuSO? 5H? O is blue vitriol which is represented as [Cu (H? O)? ]. H? O.SO? Here, secondary valencies are 4 H? O and 1H? O molecule outside coordination sphere is involved in hydrogen bonding.

Oxidation state of N
| NO | +2 |
|-|-|
| NO? | +4 |
| N? O | +1 |
| NO? | +5 |
So, order of oxidation state is
NO? > NO? > NO > N? O

Match the following:
Antifertility drug → Norethindrone
Antibiotic → Salvarsan
Tranquilizer → Meprobamate
Artificial Sweetener → Alitame

Hybridisation of carbon a, b, and c respectively are sp³, sp² and sp².

Non- biodegradable wastes are generated by thermal power plants which produce fly ash. Bio-degradable detergents leads to eutrophication by decreasing oxygen level in water.
