🤓 Based on our data, we think this question is relevant for Professor Lalancette's class at NEWARK.
The following reaction in aqueous solution was found to be first order in [OH- ], first order In [C2H5Br], and inverse first order In Br - .
C2H5Br + OH - → C2H5OH + Br -
Which one of the following mechanisms Is consistent with the observed reaction order?
A.) C2H5Br ⇌ C2H5 + + Br - fast
C2H5 + + OH - → C2H5OH slow
B.) C2H5Br + H2O → C2H5OH + H+ + Br - slow
H+ + OH - → H2O fast
C.) C2H5Br ⇌ C2H5 + + Br - slow
C2H5 + + OH - → C2H5OH fast
D.) C2H5Br ⇌ C2H5 + + Br - slow
OH - + Br - → HOBr fast
HOBr + C2H5+ → C2H5OH + Br - fast
