Question

draw the lewis structure created by the curved arrow. write in formal charges wherever they are not equal to zero. click and drag to start drawing a structure.

Explanation:

Step1: Understand electron - pair movement

The curved arrow shows the movement of the lone - pair on nitrogen towards the carbon - nitrogen double - bond.

Step2: Redraw the Lewis structure

The new structure will have a single bond between C and N, and a negative formal charge on carbon and a positive formal charge on nitrogen. The carbon has 4 valence electrons, it is making 3 bonds and has 1 lone - pair in the new structure. Formal charge on C=$4-(3 + 2)= - 1$. The nitrogen has 5 valence electrons, it is making 4 bonds and has no lone - pairs in the new structure. Formal charge on N=$5-(4+0)=+1$.

Answer:

H₃C^--N⁺H₂ (with the negative formal charge on carbon and positive formal charge on nitrogen)
