Molecular Geometry Formula Lewis structure #electron groups Bond angles) Drawing Name of shape BeF: Formula Lewis structure #electron groups Bond angle(s) Drawing Name of shape H.0 trigonal bipyramid Polar and nonpolar bonds.polar and nonpolar molecules A covalent bond is polar if the electronegativities of the two atoms are different by more than 0.4. For example, hydrogen chloride, HCL has a polar bond because electronegativity of H (21) and the electronegativity of C100) are very different (3.0-21-09. Because chlorine's electronegativity is...
