Hydration reaction
Verified step by step guidance
1
Identify the functional group transformation: The problem asks for a reaction that converts an alcohol (R-OH) into an alkene (R=R'). This involves the removal of water (H2O) from the alcohol molecule.
Understand the concept of dehydration: Dehydration reactions involve the loss of water from a molecule. In organic chemistry, this is a common method to convert alcohols into alkenes.
Recognize the mechanism: Dehydration of alcohols typically proceeds via an elimination mechanism, often E1 or E2, depending on the conditions and the structure of the alcohol.
Consider the conditions: Dehydration reactions often require an acid catalyst, such as sulfuric acid (H2SO4) or phosphoric acid (H3PO4), and heat to facilitate the removal of water and formation of the double bond.
Review the other options: Reduction reactions typically involve the gain of electrons or hydrogen, oxidation involves the loss of electrons or hydrogen, and hydration involves the addition of water. None of these processes convert alcohols to alkenes.
