1. Lewis Structure and Molecular Shape of CH\u2083Cl<\/strong><\/h3>\n\n\n\n

The Lewis structure of CH\u2083Cl (methyl chloride)<\/strong> consists of:<\/p>\n\n\n\n

    \n
  • A carbon (C)<\/strong> atom at the center, forming four single bonds.<\/li>\n\n\n\n
  • Three hydrogen (H)<\/strong> atoms each forming a single bond with carbon.<\/li>\n\n\n\n
  • One chlorine (Cl)<\/strong> atom forming a single bond with carbon.<\/li>\n\n\n\n
  • Chlorine has three lone pairs of electrons.<\/li>\n<\/ul>\n\n\n\n

    The molecular shape of CH\u2083Cl is tetrahedral<\/strong>, based on the VSEPR (Valence Shell Electron Pair Repulsion) theory<\/strong>. Since carbon has four regions of electron density around it (three H atoms and one Cl atom), these regions arrange themselves to minimize repulsion, resulting in a tetrahedral shape with bond angles of approximately 109.5\u00b0<\/strong>.<\/p>\n\n\n\n

    2. Observation on Adding a Solute Crystal to a Supersaturated Solution<\/strong><\/h3>\n\n\n\n

    Correct Answer:<\/strong> d) The solute precipitates out of the solution.<\/strong><\/p>\n\n\n\n

    Explanation (300 words)<\/strong><\/h4>\n\n\n\n

    A supersaturated solution<\/strong> is an unstable solution that contains more dissolved solute than it can normally hold at a given temperature. This state occurs when a solution is carefully prepared by dissolving excess solute at a higher temperature and then cooling it slowly without disturbance.<\/p>\n\n\n\n

    When a solute crystal<\/strong> is added to a supersaturated solution, it acts as a nucleation site<\/strong>. This disturbs the delicate equilibrium and causes the excess solute to rapidly precipitate out of the solution in a crystalline form. This happens because the solution was already holding more solute than its saturation limit<\/strong>, so the system moves toward a more stable, saturated state<\/strong> by releasing the extra solute as a solid.<\/p>\n\n\n\n

    For example, if a supersaturated sodium acetate solution<\/strong> is prepared and a tiny crystal of sodium acetate is introduced, a sudden and rapid crystallization occurs. This is often used in hot packs<\/strong>, where a small metal disk initiates crystallization, releasing heat.<\/p>\n\n\n\n

    This principle is widely used in:<\/p>\n\n\n\n

      \n
    • Industrial Crystallization<\/strong>: Purification of compounds through controlled precipitation.<\/li>\n\n\n\n
    • Rock Candy Formation<\/strong>: Supersaturated sugar solutions crystallize upon the addition of a sugar crystal.<\/li>\n\n\n\n
    • Chemical Analysis<\/strong>: Supersaturation is used to precipitate specific compounds from solutions.<\/li>\n<\/ul>\n\n\n\n

      Thus, the correct observation when adding a solute crystal to a supersaturated solution<\/strong> is that the solute precipitates out<\/strong> as the solution returns to a saturated state<\/strong>.<\/p>\n\n\n\n
