Answer:
See explanation
Explanation:
Biphenyl is formed by the reaction of two phenyl radicals. It is a major impurity ( undesired product) that is formed when some amount of phenyl bromide (bromobenzene) doesn't react solid magnesium in the formation of the Gignard reagent. In other words, it is formed when there is a coupling reaction between Grignard reagent (Grignard reagent acts as a strong nucleophile) and bromobenzene
Biphenyl is usually produces when the concentration of bromobenzene is high and when there is increase in temperature during reaction. To minimize the amount of biphenyl, it is best to add the bromobenzene solution slowly so that the reaction boils gently, since the reaction is favorable at low temperatures.
Discriminative Stimulus is the name of the stimulus which controls operant response.
<h3>What is a Discriminative Stimulus?</h3>
This is a stimulus that generates a particular kind of response when it is present and usually elicits a faster and more frequent response.
Discriminative Stimulus is usually more difficult to correct if it is negative.

I think the correct answer would be an office layout that includes open spaces. Artifacts are very obvious symbols in an organization culture. For example, the rewards for employees, the layout of the offices and how they greet visitors. Hope this helped.
