We’re being asked to draw all carbon atoms, hydrogen atoms, and lone pairs in the skeletal structure of caffeine:



Recall that in a bondline or skeletal structure:

Carbons, hydrogens, and lone pairs are implied

Formal charges are shown explicitly

Hydrogens on heteroatoms are drawn explicitly


For this problem, we need to do the following:

Step 1: Draw all carbons in the skeletal structure.

Step 2: Fill in the missing hydrogens.

Step 3: Fill in the missing lone pairs.
