| B. | Desilication |
| C. | Hydration |
| D. | Oxidation |
| Answer» C. Hydration | |
|
Explanation: When water combines chemically with other elements, the process is called hydration. In organic chemistry, a hydration reaction is a chemical reaction in which a hydroxyl group (-OH) and a hydrogen cation (an acidic proton) are added to the two carbon atoms bonded together in the carbon-carbon double bond which makes up an alkene functional group. The reaction usually runs in a strong acidic, aqueous solution. Hydration leaves the non-water component intact. |
