Answer:
If polyethylene is prepared from ethylene it changes its configuration, from sp² to sp³.
Step-by-step explanation:
A chemical reaction is characterized in that the hybridization of the carbon atom changes if the number of atoms that are attached to that atom is changed. Hybridization is characterized by being sp³, sp² and sp.
In ethylene, carbon atoms are attached to two hydrogen atoms. In this way, carbon hybridization is sp². On the other hand, in polyethylene, the double bond found in the ethylene molecule breaks, thus forming two single bonds. In polyethylene, each carbon is attached to four atoms, therefore, its hybridization is sp³.
