Question
The loss of water from an alcohol to form an alkene is called a(an) _______ reaction?
Group of answer choices:
- oxidation
- reduction
- addition
- elimination
Solution
The loss of water from an alcohol to form an alkene is called an elimination reaction.
Explanation:
-
Elimination Reaction: This type of reaction involves the removal of a small molecule from a larger one. In the case of alcohols, when water (H₂O) is eliminated, an alkene is formed. This is a characteristic transformation in organic chemistry, particularly in dehydration reactions, where the substrate (in this case, the alcohol) loses water to yield a carbon double bond.
-
Comparison with Other Reactions:
- Oxidation refers to the loss of electrons or an increase in oxidation state, often involving the addition of oxygen or the removal of hydrogen.
- Reduction is the opposite, involving the gain of electrons or a decrease in oxidation state.
- Addition Reaction involves the addition of atoms to a molecule without removing any component from it.
In summary, the correct term for the reaction where water is lost from an alcohol to form an alkene is elimination reaction.
