Question

Name the reagent in the following reaction:
\( \text{CH}_3\text{CH} = \text{CH}-\text{CN} \xrightarrow{} \text{CH}_3\text{CH} = \text{CH}-\text{CHO} \)

Hint:

Electron-withdrawing groups increase the acidity of carboxylic acids, and BF₃ is commonly used in the hydrolysis of nitriles to aldehydes.

Answer 1

The reagent is Boron Trifluoride (BF), which facilitates the conversion of the nitrile group to an aldehyde group via hydrolysis.
