  2. Sir can you plz upload the video for the reactions which include stereochemistry like OsO4, bromine water, syn anti coplaner arrangements, because from 3 to 4 years it is the trend of IIt to ask questions which include stereochemistry because it confuse the students most .. It will be really helpful for us that is u r family if u do this… so plz if possible show positive response to it…

  5. dearest sir…though i had posted a similar question on one of your neet revision videos, i didn't receive a reply… in fact that video got deleted…sir, me and possibly many others like me are not at all satisfied with our jee mains performance…we have to give other engineering entrances like bitsat and COMEDK our best shot, or else we are doomed…your revision videos were really VERY helpful,even the neet ones…please PLEASE let them be till 25 may, sir…really need those as i am weak at organic chemistry and its my last hope to make it…
    regards from an anxious yet hopeful student:)
