Which of the following is an acceptable Lewis structure for methanol (CH3OH)? H H C O H H H C=O H H H<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct Lewis structure for methanol (CH\u2083OH) is the third option<\/strong> in the image (third from the top).<\/p>\n\n\n\n

Correct Answer:<\/h3>\n\n\n\n

Third structure<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Methanol (CH\u2083OH) is composed of:<\/p>\n\n\n\n

    \n
  • 1 carbon atom (C)<\/li>\n\n\n\n
  • 4 hydrogen atoms (H)<\/li>\n\n\n\n
  • 1 oxygen atom (O)<\/li>\n<\/ul>\n\n\n\n

    Step-by-step analysis:<\/strong><\/p>\n\n\n\n

      \n
    1. Carbon forms four bonds.<\/strong>
      Carbon is in group 14 and has 4 valence electrons, so it forms 4 covalent bonds. In methanol, carbon is bonded to three hydrogen atoms and one oxygen atom.<\/li>\n\n\n\n
    2. Oxygen forms two bonds and has two lone pairs.<\/strong>
      Oxygen is in group 16 and has 6 valence electrons. In methanol, oxygen forms a single bond with the carbon and another single bond with a hydrogen atom (as in the hydroxyl group \u2014OH). This leaves two lone pairs on the oxygen.<\/li>\n\n\n\n
    3. Each hydrogen forms one bond.<\/strong>
      Hydrogen atoms have 1 valence electron and form only one bond.<\/li>\n<\/ol>\n\n\n\n

      The third option correctly shows:<\/p>\n\n\n\n

        \n
      • Carbon bonded to three hydrogens and to one oxygen.<\/li>\n\n\n\n
      • Oxygen bonded to one hydrogen and to the carbon.<\/li>\n\n\n\n
      • Two lone pairs on the oxygen.<\/li>\n<\/ul>\n\n\n\n

        Why other options are incorrect:<\/strong><\/p>\n\n\n\n

          \n
        • First option:<\/strong> Oxygen is not bonded to hydrogen, which is incorrect for CH\u2083OH.<\/li>\n\n\n\n
        • Second option:<\/strong> Shows a double bond between carbon and oxygen, which is not how methanol is structured. That would resemble formaldehyde, not methanol.<\/li>\n\n\n\n
        • Fourth option:<\/strong> Oxygen is not bonded to hydrogen again, and there is a lone pair on carbon, which is incorrect since carbon does not carry lone pairs in this structure.<\/li>\n<\/ul>\n\n\n\n

          Thus, the third structure<\/strong> is the correct and acceptable Lewis structure for methanol.<\/p>\n\n\n\n
