Which of the following reactions can alkenes undergo?

Which of the following reactions can alkenes undergo?

Step 1: Understand what alkenes are. Alkenes are hydrocarbons that contain at least one carbon-carbon double bond.
Step 2: Learn about hydrogenation. This is a reaction where hydrogen is added to the alkene, converting the double bond into a single bond.
Step 3: Understand dehydration. This reaction involves the removal of water (H2O) from an alcohol, which can be derived from alkenes, leading to the formation of alkenes.
Step 4: Know about esterification. This is a reaction where an alkene reacts with an alcohol in the presence of an acid to form an ester.
Step 5: Conclude that since alkenes can undergo hydrogenation, dehydration, and esterification, all of these reactions are applicable to alkenes.
