2,4-dinitrohydrazine used during the preparation is a base and may form hydrazonium ion in solution, for the removal of this methanol is used.
Methyl 2-methylbutyrate can be prepared by the esterification of 2-methylbutyric acid with methanol in the presence of a strong acid catalyst, such as sulfuric acid. The reaction is usually carried out under reflux conditions and the ester is then isolated by extraction and distillation.
Methanol is a commonly used solvent for extraction due to its polar nature and ability to dissolve a wide range of compounds. However, it is important to consider the toxicity of methanol and ensure proper safety precautions are taken when using it for extractions. It is also important to be aware of the regulations and guidelines surrounding the use of methanol in extraction processes.
The most common reaction is:CO + 2 H2 = CH3OH
Methoxide is your nucleophile; it will attack the C3 of 2,2-dimethyloxirane (the carbon that is attached to the oxygen, but doesn't have any methyl groups) via backside attack. This will cause the bond between C3 and the oxygen to break, thus releasing the chain and forming the oxide form of 1-methoxy-2-methyl-2-propanol. Since the oxide of this product is more basic than methanol, it will rip the hydrogen off of methanol, which will create the final product and regenerate methoxide.
ethanol Edit- this would be methanol because ethanol is a 2-carbon chain compared to the 1C in ethanol, and therefore has more intermolecular forces. As a result, molecules of ethanol would need more energy to break these intermolecular forces to be in a gaseous phase.
Methyl 2-methylbutyrate can be prepared by the esterification of 2-methylbutyric acid with methanol in the presence of a strong acid catalyst, such as sulfuric acid. The reaction is usually carried out under reflux conditions and the ester is then isolated by extraction and distillation.
The solubility of cholesterol in methanol is 0.014. 2-propanol would be a better solvent than methanol for the extraction of cholesterol from egg yolk.
When combusted, methanol releases about 22.7 megajoules of heat per liter of fuel burned.
The oxidation number of carbon in methanol (CH3OH) is -2. The oxygen has an oxidation number of -2, and the hydrogen atoms have an oxidation number of +1 each, resulting in a total charge of 0 for the molecule.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.

Rubbing alcohol typically contains isopropyl alcohol, not methanol. Methanol is a toxic form of alcohol that can be harmful if ingested or absorbed through the skin. It is important to use rubbing alcohol as intended and not ingest it.
There are far more than five. Ethanol, methanol, 2-propanol, pentane, and hexane are five extremely common examples.
The balanced chemical equation for the combustion of methanol is: 2CH3OH + 3O2 -> 2CO2 + 4H2O From the equation, 2 moles of methanol produce 2 moles of CO2. One mole of CH3OH has a molar mass of 32.04 g, and one mole of CO2 has a molar mass of 44.01 g. First, find the number of moles of methanol in 805 g. Then, use the stoichiometry of the balanced equation to calculate the mass of CO2 produced.

Methanol is the most volatile compound among the options listed. It has the lowest boiling point and highest vapor pressure compared to acetone, 2-butanone, and t-butyl chloride.
