1. Want normal bonding for all
2. C=O (or C=C in other cases) may help
3. If you have any formal charges (not here), they must sum
to net charge of molecule (zero, in this case)
4. Organization must match condensed formula sequence
1. The Nitrogen is tetrahedral, so the N-H hydrogen must
either be wedged or hashed. (The lone pair doesn't need to
be drawn in, but it impacts the shape of the nitrogen)
2. Drawing the correct Lewis structure is essential! Do fifirst!
Fine if N-H is hashed
instead of wedged
