Topic: amines of the aliphatic series.

The purpose of the work: to study the chemical properties of amines of the aliphatic series by solving problems.

 

1.Write a structural formula of a saturated Amine with a density of 1.55 AIR, consisting of 53.3% carbon, 15.6% hydrogen, and 31.1% nitrogen.

2.when applying a mass of 2.36 g of saturated Amine, 5.28 g of carbon dioxide and 0.448 L of nitrogen are formed. Its structural formula is if the density of hydrogen (vapor) of an amine is 29.5.

3. What is its molar mass if the secondary Amine chlorosutex salt contains 43.55% chlorine?

4.write down the structural formula of the amine isomers, the composition of which is С4Н11N, and name them.

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

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

6.the following amines should be placed according to the reduction of their base properties: : а) СН3NH2; б) С6Н5NH2; в) (СН3)3N; г) (С6Н5)2NH3; д)СН3-(СН2)2-NH2; е) СН3- NH- С2Н5. It is necessary to explain why the basic properties of aromatic amines are weaker than those of fat series amines.

7. name the names of amines according to the following formulas:

а) СН3-СН(NH2)-СН3         б) NH2-СО- NH2  

8.it is necessary to write down the equations of reactions of ammonia and methylamine interaction with water and describe what properties amines show. From the point of view of the electronic eye, it is necessary to explain why methylamine is a stronger base than ammonia.
