HOCl Lewis Structure

Answer:
To understand the Lewis structure of Hypochlorous acid (HOCl), follow these steps:

  1. Determine the total number of valence electrons:

    • Hydrogen (H): 1 valence electron
    • Oxygen (O): 6 valence electrons
    • Chlorine (Cl): 7 valence electrons

    Total valence electrons = 1 + 6 + 7 = 14 valence electrons

  2. Draw the skeletal structure:

    • Place the least electronegative atom (Hydrogen) at one of the ends.

    The skeletal structure will be:
    [
    \text{H-O-Cl}
    ]

  3. Place electrons around each atom to fulfill the octet rule (or duet for Hydrogen):

    • Start by placing single bonds between the atoms:
      [
      H-O-Cl
      ]

    Each single bond represents 2 electrons. We have used 4 electrons so far (2 for each bond).

    Remaining electrons = 14 - 4 = 10 valence electrons

  4. Distribute the remaining electrons:

    • Place the remaining electrons around the atoms to satisfy the octet rule for Oxygen and Chlorine and duet rule for Hydrogen.

    Oxygen needs 8 valence electrons, so after placing the bonds, it needs 4 more:
    [
    \dots H - \dots O - Cl \dots
    ]

    Chlorine is already connected by a single bond (2 electrons), and needs 6 more:
    [
    \text{H} - \text{:o:} - \text{:cl:}\dots
    ]
    This completes the distribution of all 14 valence electrons:

    H - \dots O - \dots Cl\dots \left(\text{Total Valence Electrons} = 14\right) \] 5. **Check formal charges (optional for further validation):** - Formal charges help to determine if we have the best Lewis structure: \[ \text{Formal charge} = \text{Valence electrons} - \left(\text{Non-bonding electrons} + \frac{1}{2}\text{Bonding electrons}\right) \] - For Hydrogen: $1 - (0 + 1) = 0$ - For Oxygen: $6 - (4 + 2) = 0$ - For Chlorine: $7 - (6 + 1) = 0$ 6. **Draw the final Lewis structure:** With formal charges all zero, the structure is stable:

    H - \dots O - \dots Cl\dots

    **Final Answer:** The Lewis structure of Hypochlorous acid (HOCl) is: \[ \text{H} - \text{O} - \text{Cl} \] where Oxygen (O) has two lone pairs, and Chlorine (Cl) has three lone pairs. This detailed explanation provides a step-by-step guide to understanding the electronic arrangement in the HOCl molecule.
