For a substance with the structure CH2 (double bond) CH-CH (double bond) CH-CH3, write the formulas

For a substance with the structure CH2 (double bond) CH-CH (double bond) CH-CH3, write the formulas: a) the closest homologue, b) isomer of the carbon chain, c) isomer of the position of double bonds. Give all the substances names according to the systematic nomenclature.

a) Homology – the existence of chemically similar series of substances that differ from each other by 1 several CH2 groups.

b) Isomerism – the existence of compounds of the same qualitative and quantitative composition, but differing in structure.

c) The original diene is conjugated, the other two are cumulated (double bonds are in a row) and isolated (double bonds are removed from each other).
