doubt in product B plz help @Shaquib sir
I think there is misprint N(Ch3)2 should have there instead of N(CN3)2
May be. But pls see what will be product B . I am not able to go through right mechanism
I think you can solve this by the help of option also.see h2O2 will remove Nitrogen group and from alcohol there and after heating it will form pie bond by removing H not D because removing D will require more energy.
Answer will be A
I got it thanks .
