Work Step by Step
1. Count the electrons.
a. 1x4 (C) + 1x1 (H) + 1x5 (N) = 10 electrons.
b. 1x4 (C) + 2x1 (H) + 1x6 (O) = 12 electrons.
c. 2x4 (C) + 4x1 (H) + 3x6 (O) = 30 electrons.
2. Add the bonds between the atoms, and count how many electrons are not used.
a. 10 - 2x2 = 6.
b. 12 - 3x2 = 6.
c. 30 - 8x2 = 14.
3. Add the remaining pairs of electrons to the appropriate atoms, or create double or triple bonds.
