Cannizzaro's reaction is an example of auto oxidation
- A It is a typical reaction of aliphaticaldehyde.
- B It is a reaction answered only by aromaticaldehydes
- C It is a reaction answered by all aldehydes,
- D None of the above
Answer & Solution
Correct Answer
(D) None of the above
Step-by-step Solution
Detailed explanation
Cannizzaro reaction is an example auto oxidation. Aldehydes which do not contains a- hydrogen atom such as
benzaldehyde \( \left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CHO}\right) \), formaldehyde \( (\mathrm{HCHO}) \) undergo auto-oxidation and reduction when treated with
concentrated alkali.

benzaldehyde \( \left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CHO}\right) \), formaldehyde \( (\mathrm{HCHO}) \) undergo auto-oxidation and reduction when treated with
concentrated alkali.
