Describe reduction of aldehydes or ketones to alcohols and their HCN addition to form hydroxynitriles.
Describe: a. the reduction of aldehydes and ketones, using NaBH4 or LiAlH4 to produce alcohols b. the reaction of aldehydes and ketones with HCN, KCN as catalyst, and heat to produce hydroxynitriles exemplified by ethanal and propanone
