Please explain thoroughly.
Draw the lewis structure.
Label the molecule with - and + if applicable.
Draw the molecule 2 more times so that the molecules are correctly oriented based on the partial charges (if applicable). You should have 3 total molecules.
With a dashed line (----) show how this molecule would interact. (connect partial positive to partial negative)
Identify the type/s of intramolecular forces.
For SI2 & NH3
