Comment:
Excellent Prof, very clear and focused lecture that explains everything. Anybody who didn't do well is because of their own laziness or their ineffective studying. Constant studying and practicing of textbook problems is a MUST. If you can do and understand the majority of them then you can get an A.

Comment:
He writes the notes every class, and shows how the mechanisms work very well. people say he is too hard but if you know the chemistry, then you will do well. if you hear people complaining it is because they are lazy, or dumb. if you listen in class, do the problems (until you understand the concept) then you will have no problem in chem 2020.

Comment:
i have him now...tough prof. expects far too much for his tests...the class average is horrible...im a straight A student, and im failing this class right now...he's willing to help, but its all about doing the assigned problems, which is an insane amount of work to do

Comment:
Some people found him boring but he lectured very well in my opinion. Hes the type of professor youd imagine in an Ivy league school. However, this guy is BRUTAL with marking. On the first test, for nomenclature i got the whole name right except one number for positioning and got 0/6! Also, isnt clear abou whats on the tests.

Comment:
this guy is horrible!first of all he's ridiculously boring. secondly he tells the whole class atleast 3 times that it's an easy course and anyone can get an A which is very misleading.he goes on and on in lecture about the smell and taste of compounds which is VERY irrelevant to his tests. his tests are not impossible but he hardly gives part marks

He is great! He is very enthusiastic about what he teaches, and even brings along funny props (ie. "banana bonds") to make things more interesting. I wish he taught the whole course..Potvin should take some lessons from him!!Very approachable and kind. Leznoff should be the course director-he knows its a hard course and makes it bearable!

Comment:
Every person who rated this professor as good is wrong. This guy should be forced into early retirement! Very boring, notes are poor and concepts are only vaguely explained. If you can help it, do not take this course with Leznoff. Potvin is much better!
