When phenol is treated with D2SO4 /D2O, some of the hydrogens get exchanged.The final product in this exchange reaction is
A.
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 reaction is which is formed as
The correct order of acid strength of the following substituted phenols in water at 28°C is
p-nitrophenol < p-fluorophenol < p-chlorophenol
p-chlorophenol < p-fluorophenol < p-nitrophenol
p-fluorophenol < p-chlorophenol < p-nitrophenol
p-flurophenol < p-nitrophenol < p-chlorophenol
