Draw a Reasonable Mechanism for This Reaction
This reaction is a classic example of a nucleophilic addition to a carbonyl group. The nucleophile is the hydroxide ion, and the carbonyl group is the carbon-oxygen double bond in the aldehyde. The product of the reaction is an alcohol.
Identify the Reactants and Products
The reactants in this reaction are:
- Benzaldehyde (C 6H 5CHO)
- Sodium hydroxide (NaOH)
The products of the reaction are:
- Benzyl alcohol (C 6H 5CH 2OH)
- Water (H 2O)
The physical states of the reactants and products are:
- Benzaldehyde is a liquid.
- Sodium hydroxide is a solid.
- Benzyl alcohol is a liquid.
- Water is a liquid.
Determine the Balanced Chemical Equation
The balanced chemical equation for this reaction is:
C 6H 5CHO + NaOH → C 6H 5CH 2OH + H 2O
The stoichiometric coefficients in this equation indicate that one mole of benzaldehyde reacts with one mole of sodium hydroxide to produce one mole of benzyl alcohol and one mole of water.
Suggest a Stepwise Mechanism
The following is a stepwise mechanism for this reaction:
- The hydroxide ion attacks the carbonyl carbon of benzaldehyde, forming a tetrahedral intermediate.
- The tetrahedral intermediate collapses, expelling the hydroxide ion and forming a new carbon-oxygen bond.
- The proton from the hydroxide ion is transferred to the oxygen atom of the carbonyl group, forming water.
The activation energy for the first step of this mechanism is the highest, and the transition state for this step is the most unstable.
