Phenol br2 water
WebThe phenol -OHH is a greater nucleophile so therefore is more likely to be acetylated by acetic anhydride. The carboxylic acid -OH is less nucleophilic because the charge is distributed Which compounds gave a positive FeCl3 test? Explain your results. Salicylic acid because it is a test for presence of a phenol. WebSolution Verified by Toppr Correct option is B) Bromination of phenol or its derivative can be done in the presnce of bromine water. Since OH is a strong activating group towards electropholic substitution reaction and is ortho-para directing. Thus Br will come at ortho and para of OH on the benzene ring.
