Please help me

When compound \( \mathbf{A} \) is treated with a strong base, a mixture of product \( \mathbf{B} \) and \( \mathrm{C} \) (structures intentionally not shown) results. Which base below is consistent with this energy diagram and leads to product B? \( \mathrm{CH}_{3} \mathrm{Li} \) (A) (B) (C) (D) A B C For each pair of reactions below, which reaction will proceed faster? I. III. II. I. and III. I. and IV. II. and III. II. and IV. Which of the following compounds is optically active, but starts to lose its optical activity upon aggressive heating? (Note that a Deuterium "D" behaves essentially exactly like an " \( \mathrm{H} \) " in size and reactivity, but is just a different isotope that is distinguishable from a typical hydrogen atom). (B) (C) (D) Which of the following is the most accurate depiction of a structure at the point shown on the energy diagram below? (Hint: Consider the Hammond Postulate) (A) (B) (C) (D) A
