Chemistry Question on Phenols
When phenol is treated with D2SO4/D2O, some of the hydrogens get exchanged. The final product in this exchange reaction is
A
B
C
D
Answer
Explanation
Solution
In acidic medium, phenol exists in following resonating structures.
Since, o/p positions are electron rich sites, so electrophile will attack on these site, i.e., hydrogen of these sites get exchanged by D (deuterium). Hence, the final product of the
