A molecule is <strong>polar<\/strong> if it has a net dipole moment due to asymmetrical charge distribution.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">a. <strong>BFCl\u2082<\/strong> \u2013 <strong>Polar<\/strong><\/h4>\n\n\n\n<p>BFCl\u2082 has a <strong>trigonal planar<\/strong> geometry with one boron atom bonded to one fluorine and two chlorine atoms. Fluorine is more electronegative than chlorine, so the B\u2013F bond is more polar than the B\u2013Cl bonds. Because the atoms are not identical and the geometry is not symmetrical with respect to the electronegativities, their dipoles do not cancel. This creates a <strong>net dipole<\/strong>, making the molecule <strong>polar<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">b. <strong>CH\u2083CH\u2082CH\u2082CH\u2082CH\u2082CH\u2083<\/strong> (hexane) \u2013 <strong>Nonpolar<\/strong><\/h4>\n\n\n\n<p>This is a <strong>straight-chain alkane<\/strong> with only C\u2013C and C\u2013H bonds. The electronegativity difference between carbon and hydrogen is small, and the molecule has a <strong>symmetrical structure<\/strong>. Therefore, any small bond dipoles cancel out. The molecule has <strong>no net dipole<\/strong>, making it <strong>nonpolar<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">c. <strong>TeF\u2083\u207b<\/strong> \u2013 <strong>Polar<\/strong><\/h4>\n\n\n\n<p>Tellurium trifluoride has <strong>three bonding pairs and one lone pair<\/strong>, giving it a <strong>trigonal pyramidal<\/strong> shape (similar to NH\u2083). This geometry is not symmetrical, and fluorine is highly electronegative. The lone pair on tellurium adds to the asymmetry, so the molecule has a <strong>net dipole moment<\/strong>, making it <strong>polar<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">d. <strong>GeF\u2082H\u2082<\/strong> \u2013 <strong>Polar<\/strong><\/h4>\n\n\n\n<p>Germanium tetra-atom compound with two fluorine atoms and two hydrogen atoms likely has a <strong>tetrahedral<\/strong> structure. Since fluorine is much more electronegative than hydrogen, the bond dipoles do not cancel out due to the <strong>asymmetrical placement<\/strong> of atoms with different electronegativities. The molecule has a <strong>net dipole<\/strong>, so it is <strong>polar<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Summary:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Polar: <strong>a.
