Sir you don't imagine what is the value of you in our life

[Gaurav-vnoy]

My teacher has started and ended up Optical Isomerism in 30 min and I Cant able to understand Properly at depth.Now Im satisfied.God will bless you sir.Your are great and helpful

[myselfzaidsaraf]

For those who are confused, at 1:02:31 the sulphur is not a chiral centre as it has two oxygen atoms attached to it. Sir made a mistake here

[ravikantsharma]

I am yakeen batch student but your chemistry is also better then a Chemistry teacher 😂😂😂😂 I love you sir

[carguy]

Timestamps:
9:32 Polariser
11:45 optically active substance
19:05 Dextro rotatory leavo rotatory
21:55 specific rotation
23:44 😂
25:00 how to know optically active substance
26:44 😅
31:15 😅
34:00 example lactic acid
39:50 enantiomers
44:00 chiral centre
1:04:00 chiral centers no rule

[kunaljain]

You've changed the meaning of chemistry for me . Excellent teaching.

[akshatchaturvedi]

when this was uploaded I was a student in 12th, today I am watching it as a teacher to guide my first student. sweet memories can be derived from anywhere, love you sir, aapne jo kar dia no one can do in this world. We are ready and too much glad to say we may not have Elon Musk or Warren Buffet, but we have Alakh sir, that one percent.
love you sir.

[rahulbiswas]

kush rakhna us maa ko humesa jisne hum garib bacho ke liye alokh sir ko janm diya is dharti me ...👏👏👏👏👏

[swayamtirlotkar]

1:02:46 sir it(sulphur) cannot be chiral centre bcoz it has same atom that is oxygen on both sides (up and down)

[avnijain]

Sir jee mains likhte hai magar ye advanced ke topics h...itna deep me koi bhi khi bhi nhi padhayega AAPKE LIYE ULTIMATE RESPECT H HAM SABKE MAN ME

[nanu]

BAS 1 EK YEAR BAAD.... BIG KOCHING MAI.... STUDENTS KI... BHEED KAM HO JAY THANKS SIR LUV....U....SO
...MUCH👏👏👏👏👏👏👏👏

[gfalcon]

Who dislike the video
Bas itna kehna hai kisi kabhi achha nhi Kar sakte toh bura bhi mat karo

Alakh sir love from jharkhand

[shreechaudhary]

This generation is blessed to have you sir.
The future generation will miss you and we will represent you as your shinin stars

[hanshynegi]

This lecture is three years old but now it has more value then before
OLD IS GOLD 🙂

[Theamclub]

Never been interested in studies this much like I am Thanks to alakh sir...

[kiransk]

At 1:02:30
HSO4CH3 me do oxygen sulpher se judi hai vo kaise chiral center hoga sir

[luckykhedekar]

At 1:02:30

  listen the lecture It will be a superimposable image..

Sir ne bola hai ki
1.pehle compound ki mirror image
2.Or phir first compound (jiski mirror image banayi hai) usko 180° rotate karo
3.Or phir check karo ki wo imposable image hai ya nahi....

And iss hisaab se sulphur wala compound imposable image banayega or optically active nahi

And we can clearly see that.... Sulphur is bounded with two same atoms which directly shows that the compound has not any chiral centre and thus optically inactive

[btwitsviv]

This man & his dedication towards his students is Unbelievable .

[EdushanYT]

Sir ke paid batch mai itni aachi chemistry nhi pdhai jaati...
Alakh sir ka padhaya hua dimag mai baith jata hai.❤❤
