The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule isnonpolar because the bond polarity is canceled by the symmetric tetrahedral shape. Nonpolar compounds will be symmetric, meaning all of the sides around the central atom are identical - bonded to the same element with no unshared pairs of electrons. Nitrogen is more electronegative […] The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Polar and Nonpolar molecules. To determine if a molecule is polar or nonpolar, it is frequently useful to look at Lewis structures. Check 2: If the terminal Learn to determine if SO42- is polar or nonpolar based on the polarity between bonds and the molecular geometry (shape). That’s why their bond (N-Cl) is non-polar. Tetrahedral molecules that have the same species at each corner of the tetrahedron, methane or CCl4, will be nonpolar because of its symmetry.. But if corners of the tetrahedron have different electronegativities, the molecule will be at least somewhat polar- how much so … because the electronegativities of the four bonds cancel each other Answer: SiCl4 (Silicon Tetrachloride) is a nonpolar molecule because all of the four chlorine molecules are equally spaced around the central silicon atom in a tetrahedral structure.
