Name and draw the displayed formula of the yellow … WebAddition reactions involving alkenes are reactions in which the carbon–carbon double bond is converted to a single bond and atoms or groups are added to each of the two carbon atoms. Alkenes undergo an addition reaction with halogens; the halogen atoms partially break the carbon-carbon double bond in the alkene to a single bond and add across it.
WebPropene molecules will primarily form the 2-iodopropane product, not the 1-iodopropane product, when they are combined with a hydrogen iodide reactant.
