Reaction Mechanisms

Postby 005115864 » Sun Mar 10, 2019 8:49 pm

Can someone explain to me how I would determine the molecularity of each elementary reaction in C2H5Br +OH- > C2H2OH + BR-?

Is the answer bimolecular? If not, can someone explain how I would approach this question?

I think you might actually need to know the elementary steps I dont think you can determine it from the overall reaction.

The issue with looking at the overall reaction is that some of the species may have been "canceled out" or the number reduced so you have to look at each elementary step to know how many species are in each step (its molecularity). If the equation you gave was an elementary step, then yes it would be bimolecular because it has 2 species colliding to get the products.
