Why are carboxylic acids and phenols acidic? Explain why the strongest acids are assigned the lowest pH values. Explain why phenol is more acidic than cyclohexanol. AsH3 is more acidic than NH3. Explain why. Consider the below diagram, and explain why these are ranked from mo...
Why are carboxylic acids and phenols acidic? Will NH4F be acidic, basic, or neutral in water? Explain. Explain why cations such as Fe^{3+} are considered to be acidic. Provide a chemical equation to help with your explanation. HA and HB are both weak acids although HB is the stronger ...
The study looked at the differences in the compounds between strong and weak attractors and they found that there were several different carboxylic acids that showed up more on the skin of the strong attractors than the weak attractors. Specifically, the strong attractors produced significantly higher...
The only difference with weak acids and strong acids is that the pH of a weak acid will be closer to 7 than the pH of a strong acid of equal concentration (the same applies to strong/weak bases because they both do not fully dissociate). VOTE ...
processfor making silk clothing more wrinkle resistant is by bathing silk in “an aqueous solution containing a water-soluble epoxy compound in a catalyst which may be selected from alkali metal or alkali earth metal salts of dicarboxylic acids, tricarboxylic acids, and amino carboxylic acids.” ...
The alkaloid content of tobacco leaves varies greatly depending on the soil conditions, use of fertilizers, and the degree to which the plant is ripened.[29] A number of phytosterols such as cholesterol, campesterols and alcohols, phenolics, chlorogenic acid, rutin, carboxylic acids, turpenes, ...
Alcohols tend to be oxidized to carboxylic acids when they are in aqueous enviroment. PCC was invented as a workaround to this problem:it works as a reactant in anhydrous enviroment, hence stopping the reaction at the aldheyde stage.
Fatty acid is an example of a lipid which has a hydrocarbon chain connected to a terminal carboxylic acid. It is a component of the triacylglycerol. The triacylglycerol contains one glycerol unit and 3 fatty acids. The 3 fatty acid molecules are connected to one glycerol unit by an ester ...
Fatty acid is a lipid molecule that contains a hydrocarbon portion with a terminal carboxylic acid group. The fatty acid can undergo catabolic reactions to produce ATP. The catabolic reaction for fatty acid is also known as beta-oxidation that occurs in the mitochondria. On the other hand, ...
