Components of a Homogeneous Mixture:

A homogeneous mixture is a type of mixture in which the components are uniformly distributed throughout the mixture. This means that the composition of the mixture is the same at every point within the mixture. In a homogeneous mixture, the components cannot be easily distinguished by the naked eye or by simple physical means.

Let's analyze each option to determine which sets of components form a homogeneous mixture:

a) Phenol and Water:
Phenol is an organic compound, while water is an inorganic compound. When mixed together, phenol and water form a homogeneous mixture. This is because phenol is soluble in water, and the molecules of both substances are evenly distributed throughout the mixture. Therefore, option A is correct.

b) Sugar and Benzene:
Sugar is a polar compound, while benzene is a nonpolar compound. Polar and nonpolar compounds do not mix well together, and when sugar is mixed with benzene, it forms a heterogeneous mixture. The sugar particles do not dissolve in benzene and can be observed as separate entities within the mixture. Therefore, option B is incorrect.

c) Silver Chloride and Water:
Silver chloride is an ionic compound, while water is a polar compound. When ionic compounds like silver chloride are mixed with polar compounds like water, they often form a heterogeneous mixture. In this case, silver chloride does not dissolve completely in water, and some solid particles of silver chloride can be observed in the mixture. Therefore, option C is incorrect.

d) Ethyl Alcohol and Water:
Ethyl alcohol and water form a homogeneous mixture when mixed together. Both substances are polar, and the molecules of both substances are evenly distributed throughout the mixture. Ethyl alcohol is highly soluble in water, and the resulting solution is commonly known as alcoholic beverages. Therefore, option D is correct.

In summary, the components that form a homogeneous mixture are phenol and water (option A) and ethyl alcohol and water (option D). These mixtures have uniform composition and do not separate into distinct phases.
