Which of the following statements is true regarding Cannizzaro reaction?
Options
- ASome aldehydes are converted to the respective alcohols and the salt of the respective carboxylic acid.
- BAlcohol is converted into aldehyde
- CPrimary amine is converted into isocyanide
- DAcid is converted into amine
Correct answer
A. Some aldehydes are converted to the respective alcohols and the salt of the respective carboxylic acid.
Step-by-step solution
Cannizzaro reaction is a disproportionation reaction in which aldehydes without an -hydrogen atom are treated with a strong base. In this reaction, one molecule of the aldehyde is reduced to the corresponding primary alcohol, while another molecule is oxidized to the salt of the corresponding carboxylic acid. For example, formaldehyde ( HCHO ) reacts with concentrated NaOH to form methanol ( CH₃OH ) and sodium formate ( HCOONa ). Therefore, some aldehydes are converted to the respective alcohols and the salt of the
