Why NACN provides a stronger nucleophile then HCN?

Answer 1

#"Sodium cyanide"# is formally ionic, and contains a potent #""^(-)C-=N# nucleophile.............

On the other hand, #"hydrogen cyanide"#, is an uncharged molecule, #H-C-=N#, with no negative charge to donate to an electrophile.

Answer 2

NACN (sodium cyanide) provides a stronger nucleophile than HCN (hydrogen cyanide) because it has a negatively charged CN^- ion, which is more reactive than the neutral CN molecule in HCN. The negative charge on the CN^- ion makes it more attracted to positively charged species, allowing it to attack electrophiles more readily and thus exhibit stronger nucleophilic behavior compared to the neutral HCN molecule.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
