    I'm preparing for NEET online and I have seen lots and lots of videos on various subjects. This right here is legit the best video I've ever came across during my preparation. I used to find it difficult to even watch the videos of nomenclature but this video felt something else. I don't usually comment but brother you deserve it. I can only imagine the amount work you had to do in order to include everything without missing a single important point and I'm very grateful for it. A big Thank you from the core of my heart.

    This knowledge can never be gained all in one place. We'd have had to either surf thru many websites and articles or would've had to go thru the B.Sc Chemistry books and collect what we exactly required for class 11n12 which is impossible by the way (at least for me). This video is like a granted wish! Thankyou for being our Genie, Sir.

    Like seriously, I can't even express how happy I'm with you sir..apne last mein jo bola ki teachers hume 2-3 weeks padhaye honge that's absolutely 101% right..ek toh 2-3 week leke padhate hai lekin usme bhi bohut bacho ka doubt reh jata hai..lekin teacher ho to ap jesa..apse padhke feeling aa rhi hai ki mein iupac nomenclature mein expert ho gyi hun..and please sir esi videos late rahiye please.. I'm seriously writing this to you as a helpless student.. thank you again 🙏🏻❤️

    This is really helpful for NEET-UG exam as well. Thank-you! You really saved hours of my time. With reference books & other vedio's {e.g Pradeep's New course chemistry} , This really helped me master IUPAC!
