In the context of organic chemistry, which principle is often referred to as the 'law of dominance'?
A
The principle that in a genetic cross, one allele can mask the expression of another allele.
B
The principle that in a chemical reaction, the most stable product is formed preferentially.
C
The principle that in a reaction mechanism, the step with the highest energy barrier determines the rate.
D
The principle that in a mixture of enantiomers, one enantiomer will dominate in optical activity.
Verified step by step guidance1
Step 1: Begin by understanding the context of the problem, which is organic chemistry. This field often involves principles related to chemical reactions, molecular interactions, and stereochemistry.
Step 2: Identify the term 'law of dominance' and recognize that it is typically associated with genetics, where one allele can mask the expression of another. However, in organic chemistry, this term might be used metaphorically to describe a dominant process or product.
Step 3: Examine each option provided in the problem. The first option relates to genetics, which is not directly relevant to organic chemistry. The second option refers to the stability of products in chemical reactions, which is a key concept in organic chemistry.
Step 4: Consider the third option, which involves reaction mechanisms and energy barriers. This is crucial in determining the rate of a chemical reaction, as the step with the highest energy barrier is often the rate-determining step.
Step 5: Evaluate the fourth option, which discusses enantiomers and optical activity. In organic chemistry, mixtures of enantiomers can exhibit different levels of optical activity, with one enantiomer potentially dominating. This is relevant to stereochemistry and chiral molecules.
