How do you prepare methyl 2 methyl butyrate?
Methyl-2-methyl butyrate is CH3-CH2-CH(CH3)-COOCH3, it may be prepared by reacting 2-methyl butyric acid with methanol in presence of sulphuric acid.
Is methanol good solvent for extraction?
No, due to two reasons 1- edible oils are not soluble in methanol,2- methanol is a poisoness liquid.
Why does the reaction of 2 2-dimethyloxirane with sodium methoxide in methanol gives primarily 1-methoxy-2-methyl-2-propanol?
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.
What kind of chemical reaction needs to take place so that methanol can be synthesized?
The most common reaction is:CO + 2 H2 = CH3OH
Is methanol a volatile liquid at room temperature true or false?
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.

Would methanol be a better or poorer solvent for extraction of cholesterol from egg yolk compared to 2-propanol?
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.
What is carbons oxidation state of methanol?
-2 oxidation state
How much heat does methanol give off?
2 pounds
Is methanol good solvent for extraction?
No, due to two reasons 1- edible oils are not soluble in methanol,2- methanol is a poisoness liquid.
What are the release dates for Suburban Secrets - 2007 Methanol Mystery 1-10?

What is a strOnG-smelling colorless liquid that burns easily?
Alcohols such as ethanol, methanol, and 2-propanol fit that description
Is 20 percent methanol a hazardous material?
Methanol is considered hazardous because it can cause irritation and blindness. If you drink to much methanol you can go blind. I am not sure how much quanitiy wise it is. I deal with 100% methanol and get it on my skin. It evaporates extremely fast and makes my hands feel cold. Even with gloves on the cold effect still happens. Read your MSDS in your labaratory for more information on Methanol and the concentration of methanol that you possess. In case you didn't know methanol's formula is 1 carbon and 4 hydrogen and 1 oxygen. If you add a carbon and a few hydrogens you get ethanol. Ethanol's formula is 2 carbons and 6 hydrogens and 1 oxygen. Ethanol is the alcohol is your drinking alcohol. Back in the 19th century and before this time people would try to distill ethanol but they mistakenly made methanol. They would drink drink the methanol in error and become blind because of this. This process of making homemade alcohol (moonshine) of course is illegal and still is.
