Question

“Alkenes form a homologous series" Explain.

Answer 1

$\huge\underline{\overline{\mid{\bold{\green{AnSwer}\mid}}}}$

Because alkenes are hydrocarbons with at least one carbon-carbon double bond the alkene homologous series starts at ethene C2H4. Each successive molecule in the alkene homologous series is formed by adding a carbon and two hydrogen atoms or a CH2 (methylene group) to the previous molecule.

Answer 2

Answer:

Because alkenes are hydrocarbons with at least one carbon-carbon double bond the alkene homologous series starts at ethene C2H4. ... Each successive molecule in the alkene homologous series is formed by adding a carbon and two hydrogen atoms or a CH2 (methylene group) to the previous molecule.
