In question 15 I am confused between B and D. Ie where would the substitution take place at C near Br or C away one.
I think it will substitute at para position
Br is ortho para directing(cause electron density at these positions are more)
I think option B) as ans.
What I think is br is a big atom(so it’s better at para position I guess)
Got it. THANKS @Bhuvanitha_2020
