Solute Which Is The Better Solvent? I CH3(CH2)4CH3 H C H C C H2O I C H H Ui C<\/p>\n\n\n\n

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

The better solvent between n-hexane<\/strong> (CH\u2083(CH\u2082)\u2084CH\u2083) and water<\/strong> (H\u2082O) depends on the type of solute and the nature of the interaction required for dissolution.<\/p>\n\n\n\n

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

Water (H\u2082O) is the better solvent in general, especially for polar and ionic compounds, due to its polar nature and hydrogen bonding capabilities.<\/strong><\/p>\n\n\n\n

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

1. Nature of Solvent:<\/strong><\/p>\n\n\n\n

    \n
  • n-Hexane:<\/strong> A nonpolar solvent with a linear alkane structure. It dissolves nonpolar substances effectively due to dispersion forces. Examples include oils, fats, and other hydrophobic molecules.<\/li>\n\n\n\n
  • Water:<\/strong> A highly polar solvent with a bent molecular geometry, giving it a strong dipole moment. Water forms hydrogen bonds, enabling it to dissolve ionic and polar substances, such as salts and sugars.<\/li>\n<\/ul>\n\n\n\n

    2. Polarity:<\/strong> Water is polar, with partial positive (\u03b4\u207a) charges on the hydrogen atoms and partial negative (\u03b4\u207b) charges on the oxygen atom. This makes it highly effective at stabilizing charged or polar solutes. n-Hexane, being nonpolar, cannot interact with polar solutes and thus fails to dissolve them.<\/p>\n\n\n\n

    3. Hydrogen Bonding:<\/strong> Water forms hydrogen bonds, which allow it to interact with solutes that have polar functional groups (e.g., -OH, -COOH). This property is absent in n-hexane, limiting its solvent capabilities to nonpolar solutes.<\/p>\n\n\n\n

    4. Solubility Rule:<\/strong> The principle of “like dissolves like” explains why water is superior for polar solutes and n-hexane for nonpolar solutes. Polar solvents dissolve polar\/ionic solutes, while nonpolar solvents dissolve nonpolar solutes.<\/p>\n\n\n\n

    5. Versatility:<\/strong> Water’s high dielectric constant makes it capable of weakening ionic bonds, enhancing solubility for salts and electrolytes. n-Hexane lacks this property and is primarily used for hydrophobic compounds.<\/p>\n\n\n\n

    In summary, water is the better solvent for a wide range of compounds<\/strong> due to its polarity, hydrogen bonding, and dielectric properties, whereas n-hexane is limited to nonpolar solutes.<\/p>\n","protected":false},"excerpt":{"rendered":"
