How many radial nodes does the dxy orbital have?
Zero.

How does a molecule induce a dipole in another molecule?
When it randomly has more electron density on one side, a temporary dipole is made, this slight positive charge will pull the electrons of another atom to the side closest to it.

Bonus time (+30 seconds discuss in group). Explain in simple terms how an atom of Mn is able to make a quintuple bond. Give the makeup of a quintuple bond. (how many sigma, pi, etc.
Its valence shell is the d shell. D shells have 5 orbitals, and these 5 orbitals are able to interact with another atom of Mn to make 5 bonds in between them. There are 5 unpaired electrons that can bond. These bonds are made up of 1 sigma, 2 pi and 2 delta
