Verified step by step guidance

Understand the role of selective media in organic chemistry: Selective media are typically used in microbiology to favor the growth of specific microorganisms. In the context of organic chemistry, they can be used to facilitate reactions catalyzed by these microorganisms.

Consider the options provided: The options include separating reaction products based on boiling points, enhancing solubility of non-polar reactants, favoring microorganism growth, and increasing reaction yield by providing excess reactants.

Analyze each option: Separating products based on boiling points is typically done through distillation, not selective media. Enhancing solubility involves solvents, not media. Increasing yield by providing excess reactants is a stoichiometric consideration, not related to media.

Focus on the correct purpose: The correct use of selective media in this context is to favor the growth of specific microorganisms that can catalyze certain reactions, aligning with the role of selective media in promoting specific biological processes.

Conclude with the correct understanding: Selective media are used to create an environment that supports the growth of desired microorganisms, which can then catalyze specific organic reactions, making this the correct purpose in the given context.
