In the Cannizzaro reaction of benzaldehyde ( aka solventless disproportionation of benzaldehyde in the presences of a strong bas
e such as KOH), what is the internal reduction product?
1 answer:
Answer:
Reaction products are shown below
Explanation:
- In cannizaro reaction, benzaldehyde produces benzoic acid and benzyl alcohol through disproportion.
- Here, a hydroxyl group first gives a nucleophilc addition at carbonyl center of benzaldehyde.
- Then a hydride transfer takes place to another molecule of benzaldehyde
- Thus, benzoic acid and benzyl alcohol are produced.
- Full reaction mechanism has been shown below

Answer: an increase in the concentration of in aqueous solutions and is capable of donating one or more
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions
in water.
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
Thus According to the Arrhenius concept, an acid is a substance that causes an increase in the concentration of in aqueous solutions and is capable of donating one or more
