Choose the pair of substances that are most likely to form a homogeneous solution.
N2O4 and NH4Cl
C6H14 and C10H20
LiBr and C5H12
C6H14 and H2O
None of the pairs above will form a homogeneous solution.
c6h14 and c10h20
C6H14 and H2O are most likely to form a homogeneous solution.
To determine which pair of substances is most likely to form a homogeneous solution, we need to consider the nature of the substances and their ability to mix together uniformly. A homogeneous solution is one where the components are evenly distributed on a molecular level, resulting in a single phase.
Let's analyze each pair of substances:
1. N2O4 and NH4Cl: N2O4 is a covalent compound, while NH4Cl is an ionic compound. Covalent compounds typically mix well with each other, but not with ionic compounds. Therefore, this pair is less likely to form a homogeneous solution.
2. C6H14 and C10H20: Both substances in this pair belong to the same functional group (alkanes) and have similar intermolecular forces. Therefore, they are likely to mix well and form a homogeneous solution.
3. LiBr and C5H12: LiBr is an ionic compound, while C5H12 is an organic compound. Ionic compounds are generally not soluble in organic solvents, so this pair is less likely to form a homogeneous solution.
4. C6H14 and H2O: C6H14 is an organic compound, while H2O is a polar compound. Polar and nonpolar compounds are generally immiscible, meaning they do not mix well. Therefore, this pair is less likely to form a homogeneous solution.
Based on this analysis, the pair of substances most likely to form a homogeneous solution is C6H14 and C10H20, as they are both nonpolar organic compounds that can mix well with each other.
Like dissolves like.
That is, polar solvents dissolve polar solutes but not non-polar solutes and non-polar solvents dissolve non-polar solutes.
