Question

e cyanide anion CN ̄ is poisonous and finds use as a pesticide. It is also used in gold

mining because the Au cation has an unusual affinity for cyanide, which forms a soluble

material that can be removed from insoluble minerals.

where is the negative charge likely to be located (more on the C, more on the N,

or shared equally between them?). Does this prediction agree with the Lewis

structure?
