Draw Lewis structures for each molecule listed below, then use VSEPR theory to determine their bond angles as well as their electronic and molecular geometries. Based on AEN values obtained from your lecture materials or the internet, determine the polarity of the individual bonds in each molecule and predict based on their molecular geometries, if the molecules are expected to be polar or nonpolar as a whole. COMPLETE THE TABLE BELOW AND COME PREPARED TO DISCUSS ITS CONTENTS IN LAB...

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...
