a) Interpretation: The reaction of the alkene, 2-butene, with a proton to give a carbocation is to be shown using curved arrows. The structure of the carbocation formed as also to be given. Concept introduction: The double bond in alkenes is nucleophilic. The π electrons can be donated to a proton. By donating the π electrons one of the carbons in the double bond forms a new C-H bond while the other carbon gets a positive charge resulting in a carbocation. Curved arrows start from a nucleophilic source (neutral or negatively charged) and end in an electrophilic sink (neutral or positively charged). During the flow of the electrons the octet rule must be maintained both in the source and sink. To show: Using curved arrows the reaction of the alkene, 2-butene, with a proton to give a carbocation and also to give the structure of the carbocation.
