Question

3. a. Show all possible products when 2-methylpentane is brominated with Bryhv? Indicate t ve amounts of each product formed if the relative rates of reaction of a bromine atom with an sp' C-H bond are: primary 1, secondary-80 and tertiary 1600.Xpts) b. Provide a complete arrow pushing mechanism to explain formation of the major product from the above reaction (show proper curved arrows, lone pairs as two dots and single electrons as one dot). Clearly label each distinct part of the reaction mechanism. Calculate an overall al for each step of your mechanism using the given bond energies. To make a bond is positive energy and to make a bond is negative bond energy. (X pts) Br- Br 46 H-Br 87 Me C-H 105 2°C-H 3°C-H Me C-Br 1e C-Br 2° C-Br 3° C-Br 95 92 70 68 68 67

Answer 1

? H for each step is given in left of mechanism and total ? H is -83. ( Unit is not given).

I have taken bond formation is negative and bond breaking is positive.
