Question 17 +CI-C=C-H The Lewis Structure Of C2HCl Molecule Is Given Above. Which Of The Following Statements Is False For This Molecule? Your Answer: There Are Three Sigma Bonds In The Molecule. It Has A Dipole Moment. O All Three Bonds Between Carbon Atoms Are Formed By The Side-To-Side Overlap Of Pure Atomic Orbitals. Each Carbon Atom Has Two Hybrid<\/p>\n\n\n\n

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

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

All three bonds between carbon atoms are formed by the side-to-side overlap of pure atomic orbitals.<\/strong><\/p>\n\n\n\n

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

The molecule C2HCl\\text{C}_2\\text{HCl} has the following structure: H-C\u2261C-Cl. Here’s a detailed explanation of why this statement is false and other properties of the molecule:<\/p>\n\n\n\n

    \n
  1. Bonding and Hybridization<\/strong>:\n
      \n
    • Each carbon atom in the molecule has a different hybridization state. The first carbon (connected to hydrogen) is sp-hybridized, and the second carbon (connected to chlorine) is also sp-hybridized.<\/li>\n\n\n\n
    • The triple bond between the two carbon atoms consists of one sigma bond<\/strong> and two pi bonds<\/strong>. The sigma bond is formed by the head-on overlap of sp orbitals from the two carbon atoms. The two pi bonds arise from the side-to-side overlap of unhybridized pp-orbitals.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Nature of the Bonds<\/strong>:\n
        \n
      • The statement “All three bonds between carbon atoms are formed by the side-to-side overlap of pure atomic orbitals” is false because only the pi bonds are formed by the side-to-side overlap of pp-orbitals. The sigma bond is not formed this way; it results from the head-on overlap of hybridized sp orbitals.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Dipole Moment<\/strong>:\n
          \n
        • The molecule C2HCl\\text{C}_2\\text{HCl} has a dipole moment because of the electronegativity difference between the atoms. Chlorine is more electronegative than carbon, creating a dipole directed toward chlorine. Additionally, the linear geometry does not cancel the dipole.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Sigma Bonds in the Molecule<\/strong>:\n
            \n
          • The molecule has three sigma bonds<\/strong>: one between the first carbon and hydrogen, one in the carbon-carbon triple bond, and one between the second carbon and chlorine.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Hybrid Orbitals<\/strong>:\n
              \n
            • Each carbon atom in the molecule has two sp-hybridized orbitals, which are used to form sigma bonds and hold lone pairs (if present).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

              This clear breakdown demonstrates why the statement is incorrect.<\/p>\n","protected":false},"excerpt":{"rendered":"
