future pharmacist here. thank you so much!

@Leah4sci 7 лет назад

You are welcome :)

@mahadihasan7087 6 лет назад

what do u mean

@serene9532 6 лет назад

mahadi hasan this was all pretty straightforward...consult a dictionary if you still don't get it :)

@toluwalaseogunsola4972 3 года назад

Lol same here

@derekpenner5052 Год назад

hi quick check were you able to become a pharmacist?

@Sal19 6 лет назад

you could also tell the difference between R and S by the direction of the arrow and connecting it to the way both letters R and S are written . when writing R you have to go clockwise (the upper part of it) and when writing S you have to go counter clockwise .

@Leah4sci 7 месяцев назад

good tip

@dreo149 8 лет назад

THANK YOU SO MUCH. My professor taught us how to get the R and S for the simplest molecule, then gave us an extremely complicated one for the exam.. I learned more from you in 15 minutes than I did in 2 hours with my prof.

@Leah4sci 7 месяцев назад

You're very welcome, so happy to help!

@gumaropedro1927 3 года назад

My professor makes this look so hard. So the problem is not the topic but the way some professors teach it.

@Leah4sci 3 года назад

Sometimes we need a different take to understand.

@spam035 3 года назад

I must have done some good deed in the past to be able to find your channel. Thank you so much. You are the best chemistry tutor I have ever had the chance to learn from.

@farisalnahhas363 7 лет назад

AT 11:53 does it matter where you place the hydrogen atom? For instance would there be any difference if you draw to the left of OH? Thanks

@Leah4sci 5 месяцев назад

Technically the dashes going back should be directly behind the OH group, but then you wouldn't be able to see it. As such it's customary to draw it offset to either side, right or left, to show that it's going away and into the page
