Cаrbоn Tetrаchlоride, chemicаl fоrmula CCl4 is pictured below. The 4 green spheres around the outside represent the chlorine atoms, and the central black sphere represents the carbon atom. This molecule has 4 carbon - chloride single bonds and is tetrahedral molecular geometry. The electronegativity of carbon is 2.5 and the electronegativity of chlorine is 3.0 Electronegtivity Difference Type of bond formed 0.0 - 0.2 nonpolar covalent 0.3 to 1.4 polar covalent greater than 1.4 ionic Using the information provided above, answer the below questions: 1. Is the bond between carbon and chlorine polar? Why or why not? (2 points) 2. Is the molecule carbon tetrachloride polar? Why or why not? (2 points)
