Question

Н2С = СН - СН2 - СН3Составьте структурные формулы двух изомеров и двух гомологов. Дайте названия всех веществ.

Answer 1

Гомологи:
H2C = CH - CH2 - CH2 - CH3        пентен-1
H2C = CH - CH2 - CH2 - CH2 - CH3      гексен-1

Изомеры:
H3C - CH = CH -CH3  бутен-2
H2C = C - CH3    2-метилпропен-1
          |
         CH3

Answer 2

Structural Formulas and Names of Isomers and Homologues

The given chemical formula is H2C=CH-CH3. Let's break it down and create the structural formulas and names for two isomers and two homologues.

Isomers are compounds with the same molecular formula but different structural arrangements. In this case, we can have two isomers by rearranging the atoms in the molecule.

1. Isomer 1: - Structural Formula: H3C-CH=CH2 - Name: Propene

2. Isomer 2: - Structural Formula: CH3-CH=CH2 - Name: 1-Propene

Homologues are compounds that belong to the same series and have similar chemical properties but differ by a repeating unit. In this case, we can create two homologues by adding a repeating unit to the molecule.

1. Homologue 1: - Structural Formula: H2C=CH-CH2-CH3 - Name: Butene

2. Homologue 2: - Structural Formula: H2C=CH-CH2-CH2-CH3 - Name: Pentene

Please note that the names provided are based on the IUPAC nomenclature system, which is commonly used to name organic compounds.
