Аmines of the aliphatic series.

Laboratory work № 11.

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 С_nH_2n+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.
