The goal: Study of the chemical properties of nitro compounds of aliphatic series by solving problems

1. It is necessary to write the structural formula of saturated amine with a density of 1.55 in air, consisting of 53.3% carbon, 15.6% hydrogen, 31.1% nitrogen.

2. Combustion of 2.36 g of saturated amine produced 5.28 g of carbon dioxide and 0.448 l of nitrogen.  The structural formula of amine with hydrogen density is 29.5.

3. If the hydrogen chloride salt of the secondary amine contains 43.55% chlorine, what is its molar mass?

4. It is necessary to write the structural formula and name the isomers of amines containing C4H11N.

5. The general formula of the primary amines of the fat series is СnH2n + 1NH2

 Knowing that, you need to create a formula of amines with 3 and 4 carbon atoms and name them.

6. The following amines should be arranged in descending order of basic properties: a) CH3NH2;  b) C6H5NH2;  c) (CH3) 3N;  d) (C6H5) 2NH3;  e) CH3- (CH2) 2-NH2;  e) CH3- NH- C2H5.  It is necessary to explain why the basic properties of aromatic amines are weaker than fatty amines.

7. Name the amines according to the following formulas:

 a) CH3-CH (NH2) -CH3 b) NH2-CO- NH2

8. It is necessary to write the equations of the reaction of ammonia and methylamine with water and describe the properties of amines.  From an electronic point of view, it is necessary to explain why methylamine is a stronger base than ammonia.
