I have the 2 following molecules to which I have to find the best resonance structures. The online assignment says there are better structures that I can make but I can only think of one possibility for each. Here's what I thought up:

Molecule 1: The double bond gets transfered to the carbon with the positive charge leaving the carbon beside nitrogen positive. Nitrogen donates a pair of electrons to the positive carbon and becomes positive.

Molecule 2: The double bond gets transfered to the carbon with the positive charge leaving the carbon beside oxygen positive.

Any advice?

Sounds right to me.
