Write the structural formula of :

a) 4- Ethyl -1-fluoro-2-nitrobenzene

b) p- NitroanilineHydrogen peroxide is a powerful oxidizing agent both in acidic and alkaline

medium. It can also act as a reducing agent towards powerful oxidizing agents

in acidic and

alkaline medium. However, in alkaline medium its reducing nature is more

effective.

Answer: [a]4-Ethyl-2-methylaniline | C9H13N - PubChem.

Synonyms: 4-ethyl-2-methylaniline71757-56-7...

Molecular Formula: C9H13N

PubChem CID: 19035152

Molecular Weight: 135.21 g/mol

[b] Hydrogen peroxide is a chemical compound with the formula H2O2. In its pure form, it is a very pale blue liquid, slightly more viscous than water.Hydrogen peroxide acts as a reducing agent towards powerful oxidising agents. In acidic medium: H2O2→2H⊕+O2+2eɵ In alkaline medium, however, its reducing nature is more effective

Q1

[a]When it is reduced, it acts as an oxidizing agent: H2O2+2H++2e–⟶2H2O When it is oxidized, it serves as a reducing agent: H2O2⟶O2+2H++2e– Hydrogen peroxide is considerably stronger as an oxidizing agent than as a reducing agent, especially in acidic solutions.

[b] When it is reduced, it acts as an oxidizing agent: H2O2+2H++2e–⟶2H2O When it is oxidized, it serves as a reducing agent: H2O2⟶O2+2H++2e– Hydrogen peroxide is considerably stronger as an oxidizing agent than as a reducing agent, especially in acidic solutions

[c] PbS + H2O2 = PbSO4 + H2O | Lead sulfide + Hydrogen Peroxide Reaction. Lead sulfide PbS reacts with hydrogen peroxide  H2O2 and produce lead sulfate PbSO4 and water as products. This reaction is a redox reaction.

[d] In laboratory ,dihydrogen is prepared by reaction of dil H2SO4 on granulated zinc. Granulated pieces of zinc are placed in a Woulfe's bottle and are covered with water. The bottle is fitted with a thistle funnel and a delivery tube. Conc H2SO4 is poured slowly through the thistle funnel.

[e] Under standard conditions for temperature and pressure (often abbreviated to STP), dihydrogen exists as a colourless, tasteless, and odourless gas which is highly combustible in nature. The molecular formula of dihydrogen is H2.

Q3

[a] Properties. At standard temperature and pressure, hydrogen is a colourless, odourless, tasteless and non-toxic gas. Hydrogen gas is highly flammable.

[b] 1 mole of So2 occupies a volume of 350 ml at 300 k and 50 atm pressure.For ideal gas, Z=1. As for the given gas, Z<1, it shows negative deviation, i.e., it is more compressible than expected from ideal behaviour.
