You want to convert 2-chloropentane(an alky halide) into1-pentene (an alkene). Which of the following reagents would youchoose? (A)NaOH/water (B)KOH/methanol
  (C)CH3ONa/CH3OH(D)(CH3)3COK/(CH3)3COH
- Consider the SN2reaction of butyl bromide with hydroxide ion , Assuming noother changes, what effect on the reaction rate would result fromsimultaneously doubling the concentrations of both butyl bromideand hydroxyl ion  A. No effect (B)Itwould double the rate (C)it would increase the rate sixtimes
(D) It would increase the rate four times.
5. Select the rate law for a second order reaction: (A)rate = k[RX] (B) rate =k[RX]2[OH-]
(C) rate =k[RX][OH-] (D) ratek[RX]2[OH-]2
