Functional groups in triphenylmethanol
WebFeb 23, 2024 · The answer is of course an hydroxyl substituent, a strongly POLAR functional group; i.e. (H 5C6)2CH (OH) versus O = C(C6H 5)2. And to test the polarity we might assess the solubility of each compound in weakly polar solvents, such as diethyl ether, and in a strongly polar solvent such as ethanol.... Answer link Triphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable "trityl" carbocation. Many derivatives of triphenylmethanol are important dyes.
