I'm asking this because im proving a friend wrong. I get how cyanide ions won't react in an ethanol solvent because the solvent is too reactive but why won't this?![enter image description here](https://i.stack.imgur.com/PnczV.jpg)




Cyanide ions in aq. sulfuric acid don't stay as ions very long, they get protonated to give HCN so cannot act as nucleophiles. Also aliphatic acyl cyanides are about as reactive as aliphatic acyl chlorides, both will readily hydolyse to the carboxylic acid in aq. soln.
