MCQ-202: About Nucleophilic substitution by Dr. Tanmoy Biswas (Chemistry The Mystery of Molecules). Video
#MCQ, #Phosphorusoxygenbond, #P(OMe)3, #SN2, #GOC, #CSIRNET,
In this lecture, I have discussed a MCQ (202) about the About Nucleophilic substitution reaction between the alpha bromo ester and Phosphorus nucleophile (Trimethyl phosphite). At first step, phosphorus center acts as a good nucleophile due to its softness. Later on , in presence of base, a stable carbanion is generated which acts as nucleophile to do Aldol types of reaction and finally produces the alpha,beta-unsaturated ester derivative. I have explained the reaction mechanism briefly. This video is a summary kinds of which will help you to understand the chemistry in shorter time. I believe such kinds of question-answer discussion may be useful for exams like BSMS, B.Sc, M.Sc, CSIR-NET, GATE, IIT-JAM, BARC, BHU, DU, SET, CU, IISER, NISER, NIPER, IISc etc., or bachelor and master degree equivalent exams in chemistry. I have provided links to some related videos. Audiences are requested to watch them. Thank you for watching and all the best....

About the Site ๐
This site provides links to random videos hosted at YouTube, with the emphasis on random. ๐ฅ
Origins of the Idea ๐ฑ
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. ๐ง
Challenges Faced ๐ค
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. ๐
Creating Truly Random Links ๐ ๏ธ
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube ๐บ
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. ๐
Content and Users ๐ต
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact ๐ค
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. ๐
