Question 10.4: Following the curved arrows, draw a resonance structure for ...

Following the curved arrows, draw a resonance structure for the HCONH^– ion.

Strategy Move electron pairs as indicated by the curved arrows, and calculate formal charges to reposition the negative charge.

Setup To determine the formal charge, we must first calculate the number of valence electrons on the atoms in question. The O and N atoms have six and five valence electrons, respectively.
