which term describes this reaction? h2so4 heat oh addition condensation elimination substitution

Answer:

C. elimination

Brief Explanations:

In this reaction, an alcohol (with -OH group) in the presence of sulfuric acid and heat loses a water molecule (H₂O) to form an alkene. This is characteristic of an elimination reaction where a small molecule is removed from the starting compound to create a multiple - bond. Addition reactions involve adding atoms or groups to a molecule, condensation reactions usually involve the formation of a larger molecule with the loss of a small molecule between two reactants, and substitution reactions involve one atom or group being replaced by another.
