It is because the cyclohexene is an unsaturated compound. It contain one or more carbon-carbon double bond in a ring structure and this bonding still can be reduced by adding hydrogen atoms (combustion process). Thus,it will more reactive compare to cyclohexane, a saturated compound that all the carbon atoms within it have been bond with hydrogen atoms. As the result, the cyclohexene will produces a sootier flame than cyclohexane.
The amount of soot corresponds to the degree of unsaturation. Basically, the more unsaturated a compound is, in this case, hexene contains a double carbon-carbon covalent bond, the more soot the compound produces.
In general, as the carbon to hydrogen ratio of a hydrocarbon increases, so does the sootiness of its flame and the more orange in colour is that flame. The carbon to hydrogen ratio increases from cyclohexane to cyclohexene to toulene.
