MHT CET Chemistry Question (2026) — Solution
Options
- A. Some aldehydes are converted to the respective alcohols and the salt of the respective carboxylic acid.
- B. Alcohol is converted into aldehyde
- C. Primary amine is converted into isocyanide
- D. Acid is converted into amine
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 (CH_3OH) and sodium formate (HCOONa). Therefore, some aldehydes are converted to the respective alcohols and the salt of the respective carboxylic acid. Answer: Some aldehydes are converted to the respective alcohols and the salt of the respective carboxylic acid.
