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.
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)-СН3б) 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.
