All of the following statements are correct about aldehydes andketones EXCEPT:
Correct answer: B. Aldehydes show position isomerism while ketones do not
- A. Aldehydes are easily oxidized while ketones do not
- B. Aldehydes show position isomerism while ketones do not
- C. Aldehydes can be oxidized easily by Fehling's solution while ketones do not
- D. Aldehydes react with alcohols to form acetal while ketones do not
Explanation
This statement is incorrect. Both aldehydes and ketones can exhibit position isomerism. Position isomerism in this context refers to the different locations of the carbonyl group within a molecule. For example, in the case of aldehydes, you can have different isomers like butanal and propanal, and for ketones, you can have isomers like pentanone and butanone.

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.
