Course Description

This course covers most of the basics of a first semester Organic Chemistry course that one might take as a nursing student, science major or pre-med student.  Ideally, students should have taken a year of General Chemistry as a prerequisite, although just completing first semester of General Chemistry should be sufficient. 

Students in this course have access to ample supplemental material, all of which will be found in the Resource Folders. In addition to the 18.5 hours of lectures, downloadable audio mp3 files of each lecture are included. For nearly all lectures, a Practice Assignment where you can test your understanding of the material can be found in the Resource Folder. Also included is an answer key for each Practice Assignment. Any graphs, figures or tables presented in the lectures are also available as downloadable files. The content of this course is as extensive as both of my General Chemistry courses that are also available on Udemy.

This course assumes that you have completed General Chemistry I and ideally General Chemistry II college courses. While you will not need to be familiar with all topics covered in those courses, you should have a good understanding of atomic structure, electron configuration, covalent bonding, electronegativity, Lewis Dot Structures, molecular geometry and hybridization. Being familiar with acid-base chemistry and equilibrium as it applies to acids and bases is a plus. Section 2 of this course gives a review of key General Chemistry topics needed for Organic Chemistry.  Since this course covers only the basics of Organic Chemistry, spectroscopic techniques such as Infrared Spectroscopy, Chromatography and Nuclear Magnetic Resonance are not covered. Anyone who is interested in learning about various aspects of Organic Chemistry may find this course beneficial, especially if you had no prior exposure to Organic Chemistry in your studies.

very complete and understandable also the materials is related to organic chemistry and the image that given on the board is acceptable to viewers

By William Diehl on 6/10/2025

Excellent course! Many chemistry courses are dry and boring because they concentrate only on the end products. The instructor in this course concentrates on mechanisms for product formation while reemphasizing the fundamental principles (e.g., electron migration, polar bonds, etc.) at every step. Constant emphasis reinforces learning. Highly recommended!

By Zena Amer on 2/25/2025

I absolutely loved this course! The explanations were clear, well-structured, and engaging, making complex organic chemistry concepts much easier to understand. Dr. K’s teaching style is excellent—concise yet thorough, with plenty of examples and practice problems that really helped reinforce the material. The course exceeded my expectations, and I highly recommend it to anyone looking for a solid foundation in organic chemistry!

By Rishabh Thatte on 4/25/2024

The course went super in depth and I loved how Dr. K gave real world examples of the different concepts. This made the course so much more interesting and it got me thinking about how everyday functions involve the fundamentals of organic chemistry.

Can save student's time if notes are written in advance (i.e. students do not need to wait for hand writing).

By Sok Ling Yee on 12/16/2023

I always find chemistry hard to understand. This course has makes chemistry fun to learn and easy to understand basic concept of organic chemistry.

By Ryan Samuel on 6/3/2023

absoluety wonderful, explained in a well articulated and concise manner allowing proper conception on the topics

By G L on 5/22/2023

I had done Gen Chem with Professor K before and he's always clear with his explanations. His courses are considerate towards those who lack a science background. Hope you continue to make more videos Prof. K!

By Quinton Oosthuizen on 1/23/2023

A bit slow getting into the meat and potatoes of organic chemistry, which is a good thing for people who haven't done chemistry since college. Videos are also very dense, if you take a lot of notes 1 hour of video will keep you busy for 3 hours easy.

By Robert W. Cuddihee on 3/8/2022

Dr. K. Your explanations are clear and concise. Very easy to follow and easy to see where you are going with the lecture. I am looking forward to learning more.
