Why doesnt NBS attack on the dotted place? Why did it attack only on the C adj to Benzene double bond?

Reagent Friday: NBS (N-Bromo Succinimide)
NBS has two major uses in Org 1/ Org 2: allylic bromination (the most common) and also as a replacement for Br2 in the formation of bromohydrins.
arent both places having allylic carbon atoms sir?
if you put water ion the mix you get a trans OH, double bond goes away.
fair xD
the one you are talking about, the eelctrons are going to be not available i think
but my organic is shit so will wait for someone who knows more to comment
like @!Nimay¡
cos of the phenyl group at the bottom
Ohh okay sir
benzylic vs allylic hai na sir
benzyllic prefer karta hai isliye waha gaya na?
Haan bhai your right, benzylic is more reactive than allylic thus NBS will prefer attacking there
Thank you so much!
