Viagra lone pairs

Viagra (Sildenafil) has 22 carbon atoms, 30 hydrogen atoms, 4 oxygen atoms, 6 nitrogen atoms, and 1 sulfur atom. The number of lone pairs and formal charges requires a detailed Lewis

Question: How many lone pairs are present in the chemical structure of Viagra? What is the formal charge? Can you explain the difference?

The lone pairs will come from oxygen and nitrogen atoms. Sulfur will not have a lone pair since it has already six bonds. Oxygen having only 2 bonds will automatically have 2 lone pairs while nitrogen having three bonds will automatically have 1 lone pair. Notice that the other nitrogen has 4 bonds and if we will use the formal charge formula
