Lewis Structure of CCl\u2084<\/strong><br>Carbon tetrachloride (<strong>CCl\u2084<\/strong>) consists of one carbon (C) atom and four chlorine (Cl) atoms. Carbon has <strong>4 valence electrons<\/strong>, while each chlorine has <strong>7 valence electrons<\/strong>. The total number of valence electrons in <strong>CCl\u2084<\/strong> is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon: <strong>4<\/strong><\/li>\n\n\n\n<li>Chlorine: <strong>(7 \u00d7 4) = 28<\/strong><\/li>\n\n\n\n<li>Total: <strong>32 valence electrons<\/strong><\/li>\n<\/ul>\n\n\n\n<p>The carbon atom forms <strong>four single covalent bonds<\/strong> with the chlorine atoms, using up <strong>8 electrons<\/strong> (2 electrons per bond). The remaining <strong>24 electrons<\/strong> are placed as lone pairs on the chlorine atoms.<\/p>\n\n\n\n<p><strong>2. VSEPR Theory Prediction<\/strong><br>The Valence Shell Electron Pair Repulsion (<strong>VSEPR<\/strong>) theory states that electron pairs around a central atom arrange themselves to minimize repulsion. In <strong>CCl\u2084<\/strong>, carbon has <strong>four bonding pairs<\/strong> (no lone pairs on carbon). According to <strong>VSEPR theory<\/strong>, the <strong>AX\u2084<\/strong> molecular shape corresponds to a <strong>tetrahedral geometry<\/strong>.<\/p>\n\n\n\n<p><strong>3. Bond Angles &amp; Symmetry<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bond angles<\/strong>: In a tetrahedral shape, the bond angles are approximately <strong>109.5\u00b0<\/strong>.<\/li>\n\n\n\n<li><strong>Symmetry<\/strong>: Since all four Cl atoms are identical, the molecule is <strong>perfectly symmetrical<\/strong>. This symmetry makes <strong>CCl\u2084 nonpolar<\/strong>, even though the C-Cl bonds are individually polar.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Why Not the Other Choices?<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B) Trigonal planar<\/strong> \u2013 Requires a central atom with three bonded atoms and no lone pairs (e.g., BF\u2083). CCl\u2084 has four bonded atoms, so it&#8217;s not planar.<\/li>\n\n\n\n<li><strong>C) Linear<\/strong> \u2013 Requires only <strong>two bonded atoms<\/strong> and no lone pairs (e.g., CO\u2082).<\/li>\n\n\n\n<li><strong>D) Bent<\/strong> \u2013 Occurs when a molecule has <strong>lone pairs<\/strong> on the central atom, like H\u2082O. Carbon in CCl\u2084 has no lone pairs.<\/li>\n\n\n\n<li><strong>E) Trigonal pyramid<\/strong> \u2013 Requires a <strong>lone pair<\/strong> on the central atom (e.g., NH\u2083), which carbon in CCl\u2084 does not have.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>CCl\u2084 has a tetrahedral molecular geometry<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the molecular geometry of CCl4?
