Types of Bonds and Orbitals in Molecules: NO3-, CS2, CH2O, FNO, C2F4

[MysticDude]

Hello PFers, a chemistry question that I need help with awaits!

Homework Statement

10.42 Describe the types of bonds and orbitals in the following: (a) NO₃^-; (b) CS₂; (c) CH₂O; (d) FNO; (e) C₂F₄.

Homework Equations

The Attempt at a Solution

I tried to visualize the kind of arrangement and what not for these but I did not know where to go from there.

(a).I think that there have to be sigma bonds and in the p-orbital. I'm not sure how to get the orbital though. I'm guessing for the orbital.

I don't know how to do the other ones though :(

Is there anyone that can help?

Googling for "orbitals in nitrate ion" gave this as a first hit:

Determine the Lewis structure and then use VSEPR theory. As far as I am aware...
