Write down the possible isomers of the C₄H₉NO₂ give their IUPAC names.

There are two isomers with the formula  CH₃NO₂. How will you distinguish between them?

Define tautomerism.

Two isomers having the molecular formula C₂H₅NO₂ on hydrolysis in acidic medium gives (A) and (B). Identify (A) and (B) and explain the reactions involved.

What is chloropicrin?

How will you distinguish between primary secondary and tertiary alphatic amines.

Account for the following
i. Aniline does not undergo Friedel – Crafts reaction
ii. Diazonium salts of aromatic amines are more stable than those of aliphatic amines
iii. pK_b of aniline is more than that of methylamine
iv. Gabriel phthalimide synthesis is preferred for synthesising primary amines.
v. Ethylamine is soluble in water whereas aniline is not
vi. Amines are more basic than amides
vii.Although amino group is o – and p – directing in aromatic electrophilic substitution reactions, aniline on nitration gives a substantial amount of m – nitroaniline.

Explain Levine and hauser acetylation.

Outline the preparation of (a) para nitroaniline from aniline, (b) tri bromo benzene from tribromo aniline

An organic compound 'A' on reduction gives compound 'B' which on reaction with trichloromethane and caustic potash forms 'C'. Compound 'C' on catalytic reduction given N-methyl benzenamine. Identify A, B and C and write the reactions involved.

Complete the following reaction

Predict A,B,C and D for the following reaction

Account for
i) Reduction of CH₃CH gives CH₃CH₂NH₂ while CH₃NC gives (CH₃)₂NH.
ii) (CH₃)₂NH requires two molar proportion of CH₃I to give the same crystalline product formed by (CH₃)₂N with one mole of CH₃l.
iii) Nitration of aniline with conc.HNO₃ may end up with same meta nitro product.
iv) p-toluidine is a stronger base than p-nitroaniline.

Account for the following:
(i) Nitroethane is soluble NaOH
(ii) Nitroethane reacts with nitrous acid
(iii) 2-methyl-2-nitro propane has neither of the properties.
