Question

Choose the pair of substances that are most likely to form a homogeneous solution. A. NaCl and Hg B. LiF and C6H14 C. NH3 and CH3OH D. C3H8 and C2H5OH E. Br2 and PF3

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

When a mixture contains two or more components that are evenly mixed together in a solvent is known as a homogeneous solution. And, whenever there occurs unequal distribution of components of the solvent and solute then the resulting solution is known as heterogeneous solution.

For example, when $NH_{3}$ and $CH_{3}OH$ are mixed together then there will occur hydrogen bonding between these two molecules.

But when NaCl and Hg are mixed then they will not combine with each other. Hence, the distribution will be uneven. So, the solution will not be homogeneous.

Similarly, LiF and $C_6H_14$, $C_3H_8$ and $C_2H_5OH$, $Br_{2}$ and $PF_{3}$ will also lead to the formation of heterogeneous solution.

Thus, we can conclude that out of the given options $NH_{3}$ and $CH_{3}OH$ is the pair of substances that are most likely to form a homogeneous solution.
