1) CCl₄ and H₂O:
No! Tetrachloromethane being non-polar in nature doesn't dissolve in water. Hence, when mixed they form two separate layers. Hence it doesn't give a Homogeneous Solution.
2) KCl and H₂O:
Yes! Potassium Chloride when dissolved in water ionizes to produce K⁺ ions which interacts with oxygen atom of water and Cl⁻ ions which interacts with hydrogen atoms of water. Therefore, forms a Homogeneous Solution.
3) Br₂ and CCl₄:
Yes! Bromine being non polar dissolves in non polar tetrachloromethane and forms a Homogeneous Solution.
4) CH₃-CH₂-OH and H₂O:
Yes: Ethanol and water forms Homogeneous Solution due to presence of stronger hydrogen bond interactions.

a. [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] and [tex]{{\text{H}}_2}{\text{O}}[/tex] will not form a homogeneous solution when combined.
b. KCl and [tex]{{\text{H}}_2}{\text{O}}[/tex] will form a homogeneous solution when combined.
c. [tex]{\text{B}}{{\text{r}}_2}[/tex] and [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] will form a homogeneous solution when combined.

Further Explanation:
Homogeneous solution consists of only one phase. It is formed when the substances are completely dissolved in each other. Solubility is the property of any substance that makes it soluble in other substances. It is governed by the principle “like dissolves like”.
a. [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] and [tex]{{\text{H}}_2}{\text{O}}[/tex]
[tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] is a non-polar covalent compound whereas [tex]{{\text{H}}_2}{\text{O}}[/tex] is a polar molecule. Both will not dissolve in each other. So a homogeneous solution will not be formed by [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] and [tex]{{\text{H}}_2}{\text{O}}[/tex].
b. KCl and [tex]{{\text{H}}_2}{\text{O}}[/tex]
KCl is an ionic compound that dissociates into its respective ions and [tex]{{\text{H}}_2}{\text{O}}[/tex] is a polar molecule. Both will dissolve in each other. So homogeneous solution will be formed by KCl and [tex]{{\text{H}}_2}{\text{O}}[/tex].
c. [tex]{\text{B}}{{\text{r}}_2}[/tex] and [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex]
Both [tex]{\text{B}}{{\text{r}}_2}[/tex] and [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex] are non-polar in nature and completely dissolve in each other. So a homogeneous solution will be formed by [tex]{\text{B}}{{\text{r}}_2}[/tex] and [tex]{\text{CC}}{{\text{l}}_{\text{4}}}[/tex].
d. [tex]{\text{C}}{{\text{H}}_3}{\text{C}}{{\text{H}}_2}{\text{OH}}[/tex] and [tex]{{\text{H}}_2}{\text{O}}[/tex]
[tex]{\text{C}}{{\text{H}}_3}{\text{C}}{{\text{H}}_2}{\text{OH}}[/tex] is capable to form hydrogen bonding with [tex]{{\text{H}}_2}{\text{O}}[/tex]. Both will completely dissolve in each other. So a homogeneous solution will be formed by [tex]{\text{C}}{{\text{H}}_3}{\text{C}}{{\text{H}}_2}{\text{OH}}[/tex] and [tex]{{\text{H}}_2}{\text{O}}[/tex].
