Answer

a. They form a homogeneous mixture. b. They don't form a homogeneous solution. c. They don't form a homogeneous solution.

Work Step by Step

The popular statement is like dissolves like. That is, a polar compound dissolves in the polar solvent, while a nonpolar compound dissolves in the nonpolar solvent. When like dissolves in like, the mixture formed is homogenous. a. Pentane and hexane both are non-polar. Hence they form a homogeneous mixture. b. Water is polar, and $CBr_{4}$ is nonpolar, hence they don't form a homogeneous solution. c. Chlorine is nonpolar and water is polar, so they are dissimilar compounds, and hence they don't form a homogeneous solution
