Which of the following is incorrect statement?
Correct answer: C. On dry distillation of calcium methanoate, ethanol is produced
- A. 1o alcohol on oxidation gives aldehyde
- B. 2o alcohol on oxidation gives ketone
- C. On dry distillation of calcium methanoate, ethanol is produced
- D. On dry distillation of calcium ethanoate, propanone is produced
Explanation
Option C is correct.No, on dry distillation of calcium methanoate, acetaldehyde is produced. The reaction is called dry distillation. In dry distillation, a compound is heated in the absence of air. This causes the compound to decompose into simpler molecules. The reaction of calcium methanoate is shown below: Ca(HCOO)2 → CH3CHO + CO2 Here, Ca(HCOO)2 represents calcium methanoate.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
