What is triphenylmethanol soluble in?
Triphenylmethanol (also known as triphenylcarbinol, 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.
Why is triphenylmethanol polar?
Triphenylmethanol is polar because of the electronegative alcohol substituent. Its lone pair of electrons creates a dipole, an uneven sharing of electrons, which results in its polarity.
What is the purpose of Grignard synthesis of triphenylmethanol?

Is triphenylmethanol a reagent?
Although not of major industrial importance, triphenylmethanol is a useful reagent in the research laboratory. Substituted derivatives of triphenylmethanol are intermediates in the production of the commercially useful triarylmethane dyes.
Is triphenylmethanol soluble in water?
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.

Step 1: For a 2-minute period, use a second clean syringe to transfer all of the reagent contents of vial #2 through the septum of “cap A” into the round bottom flask. Continue refluxing during the 2-minute period.
How to make a NaCl solution?
Saturated NaCl solution. Methods: Step 1: Before beginning the experiment , wrap the glassware involved in aluminum foil and place the glassware in an oven to ensure that the glassware is dry and free of water. Step 2: Obtain the glassware from the oven and unwrap the aluminum foil.
What are Grignard reagents?
Grignard reagents are considered to be organometallic reagents and are therefore usually strong Lewis bases and function as good nucleophiles. In anhydrous reaction conditions, the formation of Grignard reagents can occur when the reagent is reacted with an organic halide. As demonstrated in the lab, phenylmagnesium bromide, an organic halide, can react with methyl benzoate along with the Grignard reagent to produce triphenylmethanol. Since Grignard reagents are extremely reactive with Lewis acids such as water, precautions were taken during the lab to ensure that the reaction was not ruined due to the presence of water (Organic Chemistry I and II, 89). The phenylmagnesium bromide was prepared in order to begin the reaction and was added to the methyl benzoate. The melting point of the resulting product of the Grignard reaction allowed the purity of the product to be evaluated. Additionally, the IR peaks present in the IR spectrum of the product allowed the functional groups of the triphenylmethanol to be observed. Notably, the absence of water during the Grignard reaction allowed for the product of the reaction, triphenylmethanol, to be synthesized successfully.
How is triphenylmethanol synthesized?
In this experiment, triphenylmethanol was synthesized from the reaction of the Grignard reagent (phenyl magnesium bromide) with benzophenone (a ketone) and hydrolysis with HCL. The final product was purified and characterized using TLC and IR spectroscopy. The final product was weighed and the percentage yield calculated. All the apparatus for this experiment were kept completely dry as protons easily hydrolyze the Grignard reagent to a hydrocarbon. The melting point of triphenylmethanol was determined and checked against the recorded value to determine the purity of the product. The impurities generated in this reaction include biphenyl (from the reaction of phenyl radicals) and benzene from the protonation of the carbonation.
What is the Grignard reaction?
Grignard reaction allows the formation of carbon-carbon bonds using organometallic intermediate (Grignard reagents). Grignard reagents are prepared by reacting magnesium metal with alkyl or aryl halides in aprotic solvents such as diethyl ether or tetrahydrofuran. They have a carbon-metal bond, which changes the polarity ...
Overview
Structure and properties
Triphenylmethanol contains three phenyl rings and an alcohol group bound to a central tetrahedral carbon atom. All three C–Ph bonds are typical of sp -sp carbon-carbon bonds with lengths of approximately 1.47 Å, while the C–O bond length is approximately 1.42 Å.
The presence of three adjacent phenyl groups confers special properties manifested in the reactivity of the alcohol. For example it reacts with acetyl chloride, not to give the ester, but triph…
History
After the German chemist August Kekulé and his Belgian student Antoine Paul Nicolas Franchimont (1844–1919) first synthesized triphenylmethane in 1872, the Russian doctoral student Walerius Hemilian (1851–1914) first synthesized triphenylmethanol in 1874 by reacting triphenylmethyl bromide with water as well as by oxidizing triphenylmethane.
Synthesis
The preparation of triphenylmethanol from methyl benzoate or benzophenone and phenylmagnesium bromide is a common laboratory experiment for illustrating the Grignard reaction. An alternative starting material is diethyl carbonate.
Applications
Although not of major industrial importance, triphenylmethanol is a useful reagent in the research laboratory. Substituted derivatives of triphenylmethanol are intermediates in the production of the commercially useful triarylmethane dyes.
