Which of the following is used to convert olefins into aldehyde?
- A \(\mathrm{H}_{2}\) and \(\mathrm{CO}\)
- B \(\mathrm{H}_{2}\)
- C CO and alkyne
- D \(\mathrm{CO}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{H}_{2}\) and \(\mathrm{CO}\)
Step-by-step Solution
Detailed explanation
Aldehydes are prepared from alkene in oxo process. In presence of cobalt tetracarbonyl, alkynes react with \(\mathrm{CO}\) and hydrogen to form aldehydes.

Aldehydes are also prepared by hydroboration oxidation of alkynes.

The hydration of propyne gives acetone.
