I have this reaction: Ketone + kcn/h+ + heat How does the mechanism go? I think that without heat the -cn attacks the partially positive carbon in the ketone and then the -o grabs the +h to form a cyanohydrin.

I read somewhere that the reaction is reversible with heat but i could be wrong And how it would be the reaction mechanism but with an aldehyde Please give me more examples with reaction mechanisms with heat and without heat.

Why do you think the cyanohydrin reaction reverses with heat? Can you explain that?
