Question

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

Explanation:

1. In an addition reaction, atoms or groups are added to a molecule. Here, no atoms or groups are added.
2. In a condensation reaction, two molecules combine with the loss of a small molecule like water. This is not the case here.
3. In an elimination reaction, a molecule loses atoms or groups to form a multiple - bond. In the given reaction, an alcohol (with - OH group) loses a water molecule (H and OH) in the presence of sulfuric acid and heat to form an alkene, which is characteristic of an elimination reaction.
4. In a substitution reaction, an atom or group in a molecule is replaced by another atom or group. This is not what is happening in the given reaction.

Answer:

C. elimination
