In this video you’ll learn all about Fischer projections including what they are, how to read them, how to quickly draw and convert 3D molecules into Fischer projection and back without ever having to build a model kit.
You’ll learn a number of different methods for converting 3D to Fischer from small molecules containing a single chiral center, to complex molecules like D-Glucose containing multiple chiral centers.
You’ll also learn what happens when you rotate a Fischer Projection 90 and 180 degrees.

Tank you mam .the way you taught was really easy to understand
You're very welcome! I'm glad you found it helpful
thank you sooo mucchhhh, this is the only video i understand after hours and hours trying to understand it 😭😭
I am SO happy to help you understand it quickly and easily!
sorry,but may i know if the guess and check method,for the up down group,is it ok to put it reversely if I just check the R and S starting from the group corresponding to the 3D structure,for example,I put the CH2OH on the top in the last example, and use the guess and check method and get the fischer projection,is it equivalent to the example one? thank you
Please how do you know if you should look at the molecule from left side or right side or whether to look from the top or down?
Since molecules rotate in space, it doesn't matter if you look at it from the right or left. Just make sure the perspective lines up with whatever form you're turning it into
I really like the ways you simplify everything and have awsome mnemothech! Can you do a video about glycogenesis.. really I can’t understand..
Great video. The left/right eye method is one in which I will never understand. I'm sticking with the R/S guess/check method
Sounds like you found what works for you! Thanks for watching!
That was genuinely helpful, thank you sm. The only video/article that explained it well and in an easy manner!
So glad it was helpful!
I don't get it, 7:49 i did the guess and check method and in the left they were both s configuration but in the fisher they are both R
I don't want to know where Mr. Organic Chemistry wears his second bow tie. I knew he was a perv. 😂
😆🤦 on his neck? on the first button of his shirt?
Thankyou madam I think I am about to understand
Happy to help!
