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?
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).
Of course, I can help you with that! Although you can't access your books for reference, there are several online resources available that can assist you in visualizing and drawing the structural models of the molecules you mentioned. Here's a step-by-step guide on how you can find the information and create the diagrams:
1. Search for reliable online chemistry resources: Look for reputable chemistry websites, educational institutions' online libraries, or virtual textbooks. These resources often provide detailed information and illustrations for various molecules.
2. Find the structural formula or Lewis structure: The structural formula or Lewis structure is a diagram that represents the arrangement of atoms and bonds within a molecule. Search for the structural formulas of H2O, C2H6, NH3, and C2H4O2 specifically.
3. Understand the notation: Each molecule has its own unique arrangement of atoms and bonds. Learn about the symbols and notations used in structural formulas, such as how to represent different elements and the types of bonds between atoms (single, double, triple bonds).
4. Draw the structural models: Using the information obtained from the chosen online resource, start by drawing the central atom(s) and surrounding atoms. Connect the atoms with appropriate bonds, considering the number of valence electrons each atom possesses.
5. Account for lone pairs: Some atoms may have unshared or lone pairs of electrons. These should be represented in the structural model as well, usually as pairs of dots around the atom.
6. Review and validate: Once you have drawn the structural models, compare them to the information provided in the online resources to ensure accuracy. If available, check for any given angles or geometry of the molecule, as this is an essential component of the three-dimensional structure.
