1. Consider the SN2 reaction of butyl bromide with OH- ion.CH3CH2CH2CH2Br + OH- ? CH3CH2CH2CH2OH + Br-Assuming no other changes, what effect on the rate would result from simultaneously doubling the concentrations of both butyl bromide and OH- ion?a) No effect.b) It would double the rate.c) It would triple the rate.d) It would increase the rate four times.e) It would increase the rate six times.2. Consider the reaction of 2-chloro-2-methylpentane with sodium iodide.Assuming no other changes, how would it affect the rate if one simultaneously doubled the concentration of 2-chloro-2-methylpentane and sodium iodide?No effectIt would double the rate.It would triple the rate.It would quadruple the rate.It would increase the rate five times.3. Heating an alcoholic solution of sodium hydroxide and 1-bromopentane at 60°C yields primarily:
