While examining radical halogenation reactions, we saw that different "reaction pathways" lead to the formation of different products. How does the difference in energy between the activation barriers of rate-determining steps (ΔΔG‡) for these pathways affect the selectivity of the reactions and the products that are produced?
A. The bigger the difference in energy between activation barriers results in a less selective reaction. The reaction is "messy" and produces a more equivalent mixture of products.
B. The bigger the difference in energy between activation barriers results in a more selective reaction. The reaction is relatively "clean" and mostly produces one product.
C. The smaller the difference in energy between activation barriers results in a less selective reaction. The reaction is relatively "clean" and mostly produces one product.
D. The smaller the difference in energy between activation barriers results in a more selective reaction. The reaction is "messy" and produces a more equivalent mixture of products.
