Which of the following reaction is/are shown by ethene?

Explanation

Ethene, also known as ethylene, is an alkene with a double bond between two carbon atoms. It can undergo various reactions. One common reaction is addition reactions, where an electrophile adds to the double bond, resulting in the formation of a new compound. For example, ethene can undergo halogenation, where it reacts with halogens like chlorine or bromine to form halogenated compounds. It can also undergo hydration, where water adds across the double bond to form ethanol. Another important reaction is polymerization, where multiple ethene molecules combine to form a long chain polymer called polyethylene. These are just a few examples of the reactions that ethene can undergo.
