While the C-Cl bonds are polar covalent due to the electronegativity difference, the molecule is nonpolar because the symmetry cancels the dipoles. Understanding the Lewis structure is essential for determining molecular geometry, bond angles, and polarity. Carbon tetrachloride is a stable compound often used in industrial applications, but its toxicity and environmental impact limit its use today.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Draw the correct Lewis structure of CCl4 and then use it to answer the questions below. a) How many bonding pairs of electrons are in the Lewis Structure?
