Which of the following is used to convert olefins into aldehyde?

Options

AH ₂ and CO
BH ₂
CCO and alkyne
DCO

Correct answer

A. H ₂ and CO

Step-by-step solution

Aldehydes are prepared from alkene in oxo process. In presence of cobalt tetracarbonyl, alkynes react with CO and hydrogen to form aldehydes. Aldehydes are also prepared by hydroboration oxidation of alkynes. The hydration of propyne gives acetone.
