AQA CHEM4 Question
Hello,
In past paper mark schemes the reaction conditions for nucleophillic addition reactions using KCN or NaBH4 are 'aqueous and alcoholic'. Can someone briefly explain why this is - is it related to an intermediate?
Cheers

I understand why it would need to be aqueous but why would it need to be alcoholic?

The reagent is more soluble in an aqueous medium and the aldehyde in a less polar - more covalent medium.
