I don't take notes in class anymore. Instead I take notes on this guy. Thanks man, you're a lifesaver😤💯

This guy has been the Best, but now he's giving video whose content is not complete... Kindly post the whole videos here...

He has to make a living too, he has provided numerous examples for free; best organic videos on KZbin.

What does "rotate light" mean, from a practical perspective? What does it look like?

[@infinitegaming44]

Great question

[@norman1291]

@@infinitegaming44 I am beginning to suspect that they do not even know, and just repeat what they have been told.

[@ratatouilledrinksclorax9897]

It bends like refracted water, there will be a dark shadow over where it doesn't bend and light where it's headed. Like horizontal beak of dark and light​@@norman1291

[@jefking2158]

Enantiomers are non superimposable images so they rotate the plane of plane polarised light. In racemic mixtures there are equal quantities of both enantiomers and both rotate the plane of plane polarosed light by the same amount but in different directions< therefore cancelling optical activity

[@nrmasson1]

@@jefking2158 I do not understand what you have written.

[@FridahKananu-yj5of]

Thank you so much sir

[@Venugopal-jl2iw]

@16:10 min you had mentioned "Observed rotation of sample divided by specific rotation of pure enantiomer". Is it supposed to be "Observed specific rotation of sample divided by specific rotation of pure enantiomer"?

[@oneplusoneiseleven]

Some text book says: : R - configuration rotates in a dextrorotatory way : and other say R - configuration rotates light in a levorotatory manner Help clarify this for me Thnx🤗

[@ElaineQueen]

That's why he said the r configuration is not always associated with the (+) it can be either left or right same thing as the s configuration

[@ElaineQueen]

Depends on the specific molecule u are dealing with

[@helendesye2119]

You are really good man

For question 2 (at the end of the video) I got alpha = -1.386*10^6º.

How does rotation occurs in optical isomerism or optical reactivity?

[@oladimejioye6313]

Please do a video on symmetry operations 🙏🏽

[@oladimejioye6313]

@Ryder Chandler I was talking about symmetry operations on molecules in chemistry

[@harrypotter4051]

How to you rotate light? ? Tooo much confusion with this topic.

[@yuri_black_zero]

Good....thank you

[@hey3849]

Thanks

[@emircankocatepe9412]

can we say that mesos are also identical compunds?

[@lalisa639]

Yes

[@danos1011]

Hello, I'm a member, can you please help me? Do truxinate dimers which have a cyclobutane ring and either 2, 3 or 4 substituents on the same face have enantiomers? Sorry, just something I need to prepare and can't find the answer for!

when we rotate the trans-1,2-cyclohexanediol, does that make the molecule achiral?

[@kawanganyirenda452]

Men and Half

[@Moooooooooon.09]

Wdym

[@reenanwa]

so how do we know if it's (+) or (-)?

[@taiwo2729]

Based on the rotation
