Give the expected major product of reaction of 2,2-dimethyloxacyclopropane with each of the following reagents. a. Reaction with dilute \( \mathrm{H}_{3} \mathrm{SO}_{4} \) in methanol. c. Reaction with dilute aqucous \( \mathrm{HBr} \). d. Reaction with concentrated \( \mathrm{HBr} \). c. Reaction with \( \mathrm{CH}_{3} \mathrm{MgI} \), then \( \mathrm{H}^{+}, \mathrm{H}_{2} \mathrm{O} \) f. Reaction with \( \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Li} \), then \( \mathrm{H}^{+}, \mathrm{H}_{2} \mathrm{O} \)
