You are literally creating the future generation of doctors, engineers, and scientists. Props to you man (and everyone who takes part in the creation of these videos)

[@C-G585]

You are a God among organic chemists . My professor speaks a broken English and its hard to understand came here and its very clear. Thank you.

[@Mariiiam]

That was wonderfully explained. I don’t know how can I not understand the topic in an hour long lecture but understand it in the first 3 minutes of your video 🙏🏻❤️

[@FunTycoon134]

Thank you for explaining why the system works at the end, then it all made sense.

[@thejetsonslol]

omg You impress me with these tips! Thank you!

[@suryaprakashguthula6337]

Most Better than hours of lectures

[@gabrieldayot4921]

Thank you for the explanation and the equation sir. :)

[@mhemedmhemed-cb6gc]

Thank you for the explanation, it is really nice

[@lisettsanchez2534]

you deserve the world my good sir

[@bscc181]

This guy clear all my doubt

[@ntombieatandwa4374]

Thank you so much!🙏now I can do my assignment🤗

[@ashirwadkatkamwar5555]

Thank you so much sir ❤️

Thank you so much (Sun 20 Dec 2020, 5:17 PM)

[@alhassanmichael306]

Thank you very much Dr

[@StephanoPaskali-ir6uv]

It's awesome 💯

[@kevinsweeney2809]

Thanks dude!!!

[@sohelkhatri9571]

Nice explanation sir

[@someguy1576]

First. Also thank you. I haven’t seen anything like this before

[@subhadeepacharya6894]

nice explanation

[@ROHIT-mk3be]

good explanation sir

[@Islam_true_religion]

Very useful❤

[@Muslimkishehzadi786]

Thank u so much 🥰🥰

[@vedashreemahajan9962]

🙌Thank you!

[@abhijithtechandgaming1394]

Thank you sm

[@chikanma5021]

Thank you so mucb

[@Nadeem--ux7pt]

Sir thank you for explaining
But IHD of last shown compound is not zero...
Can you explain...

[@Grace-du2nt]

Thanks a ton sir ❤❤❤you have no idea how much you have helped me ❤❤❤

[@tomiwaadara1115]

Aren't you supposed to add the nitrogen and subtract the halogen?

[@itspchu]

That's what I'm wondering

[@Vi-lj1sn]

My textbook from 2013 said 0.5 * [2c+2-h-x+n]... so is it +1 for N and -x for halogen... did it change?

[@juliawenzinger2544]

No, your formula might actually be more helpful as it includes nitrogen and halogens if they are involved in a compound. if they are not, you simply ignore them.

[@sandyillescas708]

So clear, I want to cry

[@youssefattallah7124]

I been doing it wrong this whole time because of this video, you add the N and subtract the Halogens.

[@shim525]

No, he's right.
I think you just misunderstood and calculated it.
Let's take C9H7PBr2O3 from 8:33 of this video as an example.
If you calculate it using your method, it is [(20+1-2)-7]/2=6.
How is it? It's the same, right?

[@engineer4079]

5:45 it's epic, tq sir

[@hasmikmkhitarian7655]

idk what it is but something about this man's voice and the fact that he's teaching me Ochem so well is making me fall in love with him 🤨

[@shanicemagama8144]

seriously though, you are supposed to add the nitrogen and subtract the halogen

[@bran154]

Shanice Magama seriously though I don’t see you making all these videos. Shut up

[@redowooga6475]

Chill out dude

[@ankitgohil8287]

Degree of unsturatione of proplybenezene ?

[@ewannor]

Four:
3 double bonds + 1 ring(cyclic hydrocarbon);
using formula,
C9H12 -> (2(9)+2-12)/2 = 4

[@sukislyngstad-tn3ee]

I just became a member do I still have to see the commercials? don't judge please.

[@MyeonTokki]

you can only not see ads if you have youtube premium, i think. membership only allows you to have more videos

[@kareembagato7101]

Bruh. You add the nitrogen and subtract the halogens. Ffs made me lose points on my exam. Thanks though for the help,
