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 else can I help you with?
Why methanol is changing its colour to yellow on addition of sodium metal?
because heat excites sodium atom and move their valence electron from 3s orbital to 3p orbital as those electrons fa;;s back to 3s they emit a photon with a wave length thats why color changes to yellow.
Is methanol soluble with water cyclohexane and alcohol?
Yes, methanol miscible.
What molecule has the highest boiling point methane chloromethane or methanol?
Methanol has the highest boiling point among methane, chloromethane, and methanol. This is because methanol has stronger intermolecular forces (hydrogen bonding) compared to methane (only dispersion forces) and chloromethane (dipole-dipole forces).
What is the mass (in grams) of methanol of 9.09x1024 molecules of methanol?
The mass is 483,62 g.
What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
What happens if sodium methoxide 25 percent in methanol reacts with water?
The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.
Would the alkoxide form if an hydroxide was dissolved in methanol?
No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.
Is gel make when magnesium methoxide reaction with methanol?
No. Magnesium methoxide will react with water to form a gel. The gel is actually a cross-linked Magnesium hydroxide structure in methanol. Magnesium methoxide is typically sold/stored in dry methanol to protect the chemical as it is incredibly hygroscopic.
How you can separate acetic acid from zinc methoxide?
You can separate acetic acid from zinc methoxide by adding water, which will hydrolyze zinc methoxide to form zinc hydroxide and methanol. Acetic acid is not affected by this reaction and will remain in the solution. The zinc hydroxide can then be filtered out, leaving behind the acetic acid solution.
What is the reaction between Hydrazoic acid and Sodium methoxide solution?
sodium azide + methanol
What is the equation reaction of 2-iodohexane with sodium methoxide?
The reaction between 2-iodohexane and sodium methoxide will result in an SN2 substitution reaction. The equation can be represented as: 2-iodohexane + Sodium methoxide → Hexane + Sodium iodide + Methanol
What is the reaction of methanol with sodamide?
The reaction of methanol with sodamide (NaNH2) typically results in the formation of sodium methoxide (NaOCH3) and ammonia (NH3) as byproducts. This reaction is often used for the synthesis of sodium alkoxides.
How do you get sodium methoxide from sodium hydroxide and methanol?
NaOH + CH3OH --> CH3ONa + H2O Evaporate the solution to dryness, add more CH3OH and evaporate to dryness. you can repeat a few times to ensure the remaining solid is sodium methoxide
What would you expect to happen if sodium methoxide were added to water?
When sodium methoxide is added to water, it will undergo hydrolysis, producing sodium hydroxide and methanol. This reaction releases heat and sodium hydroxide is a strong base that can cause skin and eye irritation. Extreme care should be taken when handling sodium methoxide as it is highly reactive.
Why should sodium methoxide 25 percent in methanol be kept tightly closed when not in use?
Firstly, sodium methoxide is extremely toxic, so you want to handle it carefully without ever spilling (e.g. from an unsealed container). Secondly, methanol is hygroscopic and will pick up lots of water from the atmosphere. Water will hydrolyze sodium methoxide into methanol and sodium hydroxide. You wouldn't want your methanol to evaporate either.
Is methanol dissociation or ionization or dispersion?
Methanol is an organic chemical compound, not a phenomenon. Your question is not clear.
Reaction between sodium hydroxide and methanol?
When sodium hydroxide reacts with methanol, a neutralization reaction occurs, forming sodium methoxide and water. The balanced chemical equation for this reaction is: CH3OH + NaOH → CH3ONa + H2O
