Write formulas for two isomers and two homologues for a substance: CH₃ – CH₂ – CH = CH – CH₃

Let’s execute the solution:
1.CH3 – CH2 – CH = CH – CH3 – pentene – 2 (C5H10).
2. Let’s compose the formulas of homologues of this substance, General formula: CnH2n;
C6H12 hexene; С7Н14 – heptene.
3. Let us write down the structural formulas of the isomers:
H3C – CH = CH – CH2 – CH3 – pentene – 3;
H3C – CH – (CH3) – CH = CH2 – 2 – methyl butene – 2.
