Question: are ccl4 and ch4 nonpolar molecules?
Answer: According to the Lewis structure, CCl4 is a tetrahedral molecule. The electronegativity for C is 2.5 and Cl is 3.0, resulting in a polar covalent bond. ... The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is canceled by the symmetric tetrahedral shape.
