Is there anyone who has got a whole lot of stuff to do, or is it just me???☹️
Btw, In Organic Chemistry, do we remember only the things (reactions) given in syllabus? There are a lot of other reactions in the book as well....Damn..

Do you ever wonder what those people might be doing right now in life? The ones who answered questions 6-7 years ago? And people around 1-2 years ago comment on their responses to "correct" them or whatever XD but seriously, do any of you wonder? (yeah i kinda lost it)

Are there any papers having some good practical chemistry questions?
I am a bit weak at it..So😅😅

hey guys now when bromine is added to ethene and ethyne, it is given in dalal that brown colour of bromine is discharged which serves as a test for unsaturation 1) bromine is getting added to the unsaturated compound, then how can it be released 2) the reddish brown liquid bromine obtained when passed through alkyne makes it colourless, is this also the case for alkenes? because in 2015 paper this is the question asked STATE AN APPROPRIATE OBSERVATION WHEN THE GASEOUS PRODUCT OBTAINED BY DEHYDRATION OF ETHYL ALCOHOL IS PASSED THROUGH BROMINE WATER

What to study from practical work ???
 Any suggestions .....
