Final answer:
To convert an alkane to an alkene, you can use reactions such as hydrogenation, halogenation, or dehydration of alcohols.
Step-by-step explanation:
To convert an alkane to an alkene, you can use various reactions such as hydrogenation, halogenation, or dehydration of alcohols. Hydrogenation involves adding molecular hydrogen to an alkene to produce an alkane. Halogenation involves adding halogens, such as bromine, to an alkene. Dehydration of alcohols removes water to convert alcohols to alkenes.
