Upon combustion,ethene (C₂H₄)is converted to carbon dioxide and water.What change in the hybridization of carbon occurs in this reaction? A) sp to sp² B) sp² to sp³ C) sp³ to sp D) sp² to sp E) sp³ to sp²

Question

Quizplus · Accepted Answer

In ethene, the two carbon atoms are sp2 hybridized, with one unhybridized p orbital that forms the pi bond between them. Upon combustion, one carbon atom bonds with two oxygen atoms to form carbon dioxide, while the other carbon atom bonds with two hydrogen atoms and an oxygen atom to form water. This results in the loss of the pi bond, and the remaining carbon atom becomes sp hybridized with a linear geometry, allowing it to form the double bond with one of the oxygen atoms in carbon dioxide. Therefore, the hybridization of carbon changes from sp2 to sp. Choice D correctly describes this change, as it states that the carbon changes from sp2 to sp.
