For last one Q4.
I also had same doubt
Btw which center paper is this ??
Can someone explain Q4
For 1st ques i think first is dehydration with rearrangement followed by epoxide formation O18 used then hydrolysis Sn1 mech
Reason was given that BF3 doesn't removes out as it was earlier but reacts to form hbf3 x so it's not catalyst
In q4 is bf3 a catalyst
Chetan can u post all ques for 1st pic
Is prt ans.? Just asking
Ans written sidewise
I got the answer for first one. Its baeyer villigar oxidation
Woh to ketone mai hota hai yaha ketone kaha ban rha hai?
Aur bayer villegar mai bhi O18 hi attach hoga
Sorry My mistake.
You posted the correct solution for Q1 in #5. I confirmed it from one of my teachers
And what does Se do in the very last step
And mno2 one?
It's just a oxidizing agent
