Question

Consider two organic compounds with the molecular formula C5H10, one of which is a cyclic alkene and the other one is an acyclic alkene. Both of them exhibit positional isomerism as well. Identify the two compounds and draw their structural formulas.

Answer 1

The two organic compounds with the molecular formula C5H10 are cyclopentene  cyclic alkene  and 2-pentene  acyclic alkene . Both of these compounds exhibit positional isomerism.1. Cyclopentene:Cyclopentene is a cyclic alkene with a five-membered ring and one double bond. Its structural formula is as follows:   H H H    | | |H-C-C=C-C-H    | |    H H2. 2-Pentene:2-Pentene is an acyclic alkene with a carbon chain of five carbons and one double bond between the second and third carbons. Its structural formula is as follows:H H H H H | | | | |H-C-C=C-C-C-H | | | | | H H H H HThese are the two organic compounds with the molecular formula C5H10 that exhibit positional isomerism.
