Consider the reaction of 3-bromohexane with OH^- where the sterocenter exists in the "R" conformation. Which of the following statements is TRUE?
a) In an S_N2 mechanism the bromine will leave on it's own in the first step
b) If the reaction goes through a carbocation intermediate there will be a 50/50% mixture of the "R" and "S" isomer for the product
c) An S_N1 mechanism will be a one step process
d) A 50/50% mixture of the "R" and "s" stereocenter will be found if the reaction follows an S_N2 mechanism
e) The hybridization of the oxygen atom changes from one hybridization in the reactants to another hybridization in the products
