UBC CHEM 233 is an organic chemistry course designed for biological science major in UBC. It basically covers major concepts of classic organic chemistry I and II (but not all concepts) for an undergraduate degree. The major topics is covered by this course are structure, bonding, functional groups, stereochemistry, aromaticity,  acidity/basicity, SN2, SN1, E2, E1, alkenes addition, reduction and oxidation reactions, nucleophilic addition to aldehydes and ketones, carbohydrates, nucleophilic acyl substitution of carboxylic acid and their derivatives and radical reactions.



My teaching/tutoring is focused on building a solid foundation  for organic chemistry students. Four major bases that every student should know are bonding, hybridization, acid/base and resonance. I elaborate every concept of this course in details using a series of examples and I would provide students with extra practice files (PDF format) related to CHEM 233 for more practice and preparation for two midterms and final exam. I tutored more than 200 students with very good results either for weak students who wanted to pass the course or for strong students who wanted to achieve high grades such as A+ or A. The most important point about the study of CHEM 233 is to start early in order to avoid getting behind in the course. I highly recommend to use the course textbook (Organic Chemistry, Dr. David Klein) at every point of this course as a good reference to look at for your initial study and practice. For Summer semester for CHEM 233 you need to study from the beginning of the semester as the semester duration is for 6 weeks.




CHEM 205 is a physical chemistry chemistry course for general science in UBC. The course covers topics such as thermodynamic laws, solution chemistry, electrochemistry, spectroscopy and kinetics.  I tutored more than 100 students in this course with very good results. I explain all course concepts in details and work with students on practice problems and course assignment for mark. In particular the practice would focus also on multiple-choice questions that create troubles for most students. I provide extra practice files for each chapter of the course. As this course has only one midterm and final exam weighs about %65 of the overall mark, it is very wise to continue the paste of study during the semester from the beginning of the semester.


UBC CHEM 121/120 and 123/130:


CHEM 121 and 123 are general chemistry courses and bases for CHEM 233 and CHEM 205. CHEM 121 in particular is related to bonding, Lewis structures hybridization and resonance concepts among the others, so it is important to understand these concepts well in order to have a strong basis for CHEM 233. Chem 123 has two sections, first section is the physical chemistry and the second section is an introduction to organic chemistry (Lewis structures, resonance, acid/base, stereochemistry, SN1 and SN2 reactions). I tutored more than 50 students in CHEM 121 and CHEM 123 with very good results. My main focus for both courses is establish a strong foundation for students who later want to take CHEM 233 and 205 successfully.

UBC CHEM 203/223, 213 and 330:

The above organic courses are designed for chemistry and biochemistry (only CHEM 203/223 and CHEM 213) major and cover all classic organic syllabubs of an undergraduate degree. I tutored more 25 students in these chemistry courses. The main point of study is to learn from basics in CHEM 203 and build up your knowledge as you go to higher level CHEM 213 and finally the advanced level CHEM 330.
