In this lecture we will begin looking at the three dimensional shapes of molecules and learning the name associated with these structures. Fro example, the simplest hydrocarbon, methane CH₄, carbon is the central atom and it's covalently bonded to four hydrogen atoms.

Methane:

This molecule has 4 bonded atoms and it's molecular geometry, or the arrangement of atoms around a central molecule, is called tetrahedral.

This is just one of several molecular geometries you will learn in this lecture. You will be exploring more geometries in the discussion worksheet #10 also.
