Basics Chemical Bond & Lewis Structure

A step-by-step solution for YOUR own homework problem!

a. For inorganic or some organic components, the program will explain how to draw Lewis Structures step by step

b. Show possible Resonance Structures.

c. Predict Molecular geometries with VSEPR theory.

d. Predict whether a given molecule has a non-zero dipole moment and directional bond polarities based on the electro-negativities of the associated atoms.

e. For diatomic molecules (both homonuclear and heteronuclear), display the MO energy diagrams, while for polyatomic molecules , show the hybrid orbitals

f. Save the step by step Lewis structure results to file

g. Use our pull-down menu of metal cations and nonmetallic anions to form binary compounds and to find out both the formula and name of the compound

The Lewis Structure Summary

1. Determine the arrangement of the atoms in the molecule or polyatomic ion

2. Determine the total number of valence electrons present

3. Draw a single covalent bond between the central atom and each of the surrounding atoms

4. Complete the octets of the atoms bonded to the central atom

5. Place any remaining electrons on the central atom

6. Multiple bond and resonance structure
