The flavor of beer can be tainted by a trace contaminant, called ortho-bromophenol. To reduce the incidents of contamination, beer manufacturers have used certified beer flavor standards to train professional beer tasters to recognize the flavor of ortho-bromophenol. Preparing these certified standards requires pure samples of ortho-bromophenol. Propose a synthesis of ortho-bromophenol starting from phenol. (Org. Synth. 1934, 14, 14.) In a reaction, a reactant with the SMILES string Oc11 yields a product that has the SMILES string Oc11Br. Choose from the reagents below. To record your answer, place the appropriate letter in each box below. Enter only one letter in each box. Each reagent can be used more than once. a) dilute NaOH
b) Br2, FeBr3
c) HNO3
d) conc. fuming, 1 mol H2SO4
e) Zn
f) HCl
g) HBr
h) Dilute H2SO4
i) Br2

answer; /// i do believe that the correct answer is (a) boiling

the dissolution of polymer can be thermodynamically described in 2 steps.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
