Question

Select the rate law for the following reaction, e.g., CH_3CH_2CH_2CHBrCH_3 + OH^- rightarrow CH_3CH_2CH_2CHOHCH_3 + X (RBr) Rate = k [RBr] Rate = k (RBr] [OH^-] Rate= k [RBr]^2 [OH-]^2 Rate = k [RBr]^2 [OH^-]^2 Consider the S_N2 reaction of 2-iodopentane with CH_3CO_2 ion. Assuming no other changes, what effect on the rate would result from simultaneously doubling the concentrations of both 2-iodopentane and CH_3CO_2^- ion? No effect. It would double the rate. It would triple the rate. It would increase the rate four times. It would increase the rate six times. What would be the major product(s) of the following reaction? I II III IV None of the above

Explanation / Answer

1) since it is a SN2 reaction,  the rate depends on both RBr and OH- so the correct answer is B

2) since it is a SN2 reaction , if we doubling the concentrations of reactants then the rate increased four times so the correct answer is D

3) since it is a SN2 reaction the comming nucleophile will attack from the opposite side of the leaving group so the correct answer is A
