WebThe carbohydrate content of unknown biologic products can be determined by a very simple and fairly reliable procedure. This method does not include previous hydrolysis of the sample and liberation of the constituting monosaccharides, but uses concentrated sulfuric acid in the presence of phenol. Carbohydrates form either furfuraldehyde or its ... WebThe correct option is A 2,4,6−Trinitrophenol. Phenol first reacts with concentrated sulphuric acid which converts it to phenol-2,4-disulphonic acid and then with concentrated nitric acid to get 2,4,6−Trinitrophenol. It is beacause −OH is a strong activating group towards electrophilic substitution. So it forms 2,4,6−Trinitrophenol ...

WebScope of Reaction. The order of reactivity of alcohols is 3° > 2° > 1° methyl. The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive). The reaction is acid catalyzed. Alcohols react with the strongly acidic hydrogen halides HCl, HBr, and HI, but they do not react with nonacidic NaCl, NaBr, or NaI. lct incWebAction of conc.
