I need to draw structural models of atoms with stable molecules using a diagram for H20, C2h6, NH3, and C2H4o2. Since we cannot bring home our books, and I cant seem to find the answers to my questions online, How am I supposed to see an example? Can you help?

Answer 1

I think that all that is needed are simple ball and stick drawings. Here is one for water

Try to give structural formulae correctly

H2O (not 0),
C2H6 (not h),
C2H4O2 (not o)

There are a couple of stable isomers of C2H4O2 and you will need to choose one to draw. The obvious one is CH3COOH (ethanoic acid), but you could also have
HCOOCH3 (methyl formate or methyl methanoate).
