Question

The molecules of the alkene family are represented by a general formula C_nH_2n. Answer the following:

Write the molecular formula of lower and higher homologues of an alkene which contains four carbon atoms.

Answer 1

An alkene with four carbon atoms is C₄H₈.

∴ Lower Homologue is C₃H₆.

∵ Neighbour members differ by CH₂.

Higher Homologue is C₅H₁₀.
