Which is Lewis acid and base?
1.) Determine
a)CN- (is it Lewis acid or base)
b)MgBr2 (is it Lewis acid or base)
Write acid-base reaction for both CN- and MgBr2 and show how electrons shifted.
It would be a great help if you could just tell me if I'm right assuming that CN- is a base and MgBr2 an acid, I'm not sure how to write the reactions...

If we look at the standard reaction for a Bronsted acid,
So which species has donated the electrons, and which species has accepted the electron to form the
Now you have given us
Given what I have said, clearly cyanide anion is the electron pair donor, and therefore is the Lewis base.
The designation of
The magnesium ion is solvated by several water molecules, so that we could reasonably represent this as
