@@saiteja6742 tqqq teja ji as my sis Rashmi sinha is also preparing for gpat so I always discusss some topic with her as I am doing my msc chemistry and this spectroscopy matches in both of our syllabus
At 10.00 initially you formed radical at 2 degree then....on this page you made on 1 degree carbon. Why you did that and how do we know from where should we make cation n radical ??? 2) question : .... How did you do the rearramgement. I didnt get that part. You didnt combine the radical. What actually you did there. Will you please help me with this doubt
1. MCLAFFERTY rearrangement is the transfer of gama H to the terminal atom of unsaturated system and it would be a transfer of radical hydrogen, so radical must be on primary carbon (you may also try to put + on primary carbon but be careful mechanism would ionic to move electrons) however what I have written is also fine, one may write in any form. 2. To understand McLafferty rearrangement in detail, see fragmentation of carbonyl compounds in the same playlist.
It's a simple mass spectrum, plz go through the link and apply concepts which I have explained in my video of mass spectrum of Alkane. chem.libretexts.org/Bookshelves/Organic_Chemistry/Supplemental_Modules_(Organic_Chemistry)/Spectroscopy/Mass_spectrometry_1#:~:text=The%20mass%20spectrum%20of%20dodecane,over%20all%20the%20covalent%20bonds.
sir why the intensity of M-15 is more than M-29 ...allylic carbocation is resonance stabilized so it seems to have higher intensity than M-15... plz explain
M-15 is formed by the loss of methyl radical forms allylic cation which is even more stable than allylic carbocation which is formed by M-29, you can do fragmentation and compare the stability of two allylic carbocation in the light of GOC (General Organic Chemistry).
Improved my understanding through these lectures ..Thank you sir!
It's nice sir.... Accept my appreciation from Pakistan
Best vedio i found for mass spectroscopy , best wishes from srilankan 😘
Very easy and excellent... points are discussing..
very clear explanation 👍👍..thank you so much sir🙏😊😊
Very accurate,detailed and clear,,, thanks
Your explaination is excellent sir....
very nice sir...thank you please take more examples
I qualified in Gpat bcz of these lectures sir..217 rank in gpat ..all credits goes to u sir..
Thank you very much, God bless you, it's all your effort credit always goes to the students.
Sai Teja pls tell me in short which subject u studied from tetrahedron chemistry means except your pharmacology .phseutic and medicinal

Sir ❤️❤️ really u great ❤️❤️I want basics of chemistry video sir pls do it for us ❤️❤️
Very nice video sir
Really super explaination.

@@TETRAHEDRONCHEMISTRYCLASSES sir, in pent 2 ene could u plz tell us how ethene molecule is removed ?
sir, as far as i know. radical molecule will not be detected in MS right? the molecule you shown with m/z 42, isnt it radical ?
Right
Sir could you plzzz explain the fragmentation pattern in dodecane?

Could you explain the rest peaks of limonene, Please!!
Will try
👌👌👌
24.44 yeh fragment 93 ka nai balke 95 ka ho ga.
Yes it is m/z 95 and the same ion may rearrange to give C7H9+ (toluenium ion) m/z 93...
😘😘
