A student writes the following explanation of how one type of compound is formed. these compounds are made by the repeated joini
ng of one smaller unit to the end of a growing chain. the units are generally alkenes, which retain all their atoms in the chain. a compound which undergoes a similar process is polyethylene. which process is being described? condensation polymerization addition polymerization dehydrohalogenation dehydrogenation
In the given question according to the information the process of polymerization is an addition polymerization.
<h3>What is polymerization?</h3>
Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.
In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.
In condensation polymerisation removal of water molecule or any other molecule takes place.
In dehydrogenation polymerisation removal of hydrogen molecule takes place.
In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.
Hence given process is an addition polymerisation.

Answer: An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.
