Draw an alternative Lewis (resonance) structure for the compound Show the unshared pairs and nonzero formal charges in your structure. Don't use radical.
H2C=NH2
formal charge on N is +1 but i am lost now. Where to start resonance.

With H2C=NH2 the Nitrogen has a positive charge because it has 4 bonds and so you can resonate the double bond on to the positive charge forming a C-N but with a positive charge on the carbon because it only has three bonds, those are your two resonance structures.
