WebMay 20, 2024 · 1) Since the − O H of the phenol is quite acidic, it undergoes rapid H X + / D X + exchange with the D X 2 O. My expectation is that the − O H signal from the original phenol will get reduced and broadened (maybe even disappear, but I am not sure) because it is replaced with an − O D group. WebHeavy water is water with the isotope deuterium in place of ordinary hydrogen, and its formula is D2O. The above reaction can be used to produce heavy ammonia, ND3 (g), according to the equation, Li3N (s)+3D2O (l)-->ND3 (g)+3LiOD (aq) Calculate how many grams of heavy water are required to produce 490.0 mg of ND3 (g).

Water is one of the most important factors that determine the quality of edible oils. A water content of more than 0.2% (2000 μg/mL) in refined oil substantially enhances hydrolytic reactions and subsequently accelerates auto-oxidation and rancidity reaction, resulting in off-flavor and the reduction of smoke point of the oil.

WebGood question! One way to think about this is as an acid-base equilibrium with competition between two acids – H₃O⁺ and the protonated 2-methylpentan-2-ol. If you consult a pKa table§, then you will find that protonated organic alcohols typically have pKa values around -2, while H₃O⁺ has a pKa of -1.7.
