Name according to the systematic nomenclature of the substances whose formulas are given: CH3-NH-CH3. CH3-CH2-CH-COOH

1) It is necessary to determine which class of organic compounds this substance belongs to:

Structural formula: CH3 – NH – CH3 – the substance contains nitrogen and does not contain other heteroatoms, which means it is an amine.

Two methyl groups are attached to one nitrogen atom, which means it is dimethylamine.

2) In this condition, there is an error, the 4th valency is not occupied at the carbon atom following from the carboxyl group, most likely there is a substituent there, for example: CH3–, NH2–, HO– groups.

Let’s consider the possible options:

CH3 – CH2 – CH2 – COOH – contains a carboxyl group, which means it is an acid, according to the nomenclature – butanoic acid (4 carbon atoms in the chain).

CH3 – CH2 – CH – COOH – amino acid – 2-aminobutanoic acid.

NH2

CH3 – CH2 – CH – COOH – hydroxy acid – 2-hydroxybutanoic acid.

HE

CH3 – CH2 – CH – COOH – carboxylic acid – 2-methylbutanoic acid.
