George asks…
why is it far better to use diethyl ether when performing trimyristin extraction from numeg as a substitute of acetone or?
why is it better to use diethyl ether when doing trimyristin extraction from numeg rather of acetone or ethanol? does it have to do with the solubilities of trim. in every of these solvents? how would you rank trimyristin's solubility in every single of these solvents?
ItIsAllHere answers:
Hmm, i wonder why you would want to do that?
Critically although, i would say it was to do with flammability and possibly toxicity, but which is just a guess.
Chris asks…
When you create salicylic acid-naphthalene mixture in a diethyl ether with a saturated aqueous sodium bicarbonate?
When you include salicylic acid-naphthalene mixture in a diethyl ether with a saturated aqueous sodium bicarbonate answer, what type of fuel do they kind?
ItIsAllHere solutions:
CO2(g) is progressed...
Here's the well-balanced equation.
C6H4(OH)-COOH (salicylic acid) + NaHCO3 (sodium bicarbonate) --> C6H4(OH)-COO-Na+ (sodium salicylate) + CO2 (carbon dioxide) + H2O
A wash with aqueous sodium barcarbonate solution is typically performed to get rid of any unreacted acidic reagent (salicylic acid, in this situation) from the reaction combination. As you can see, salicylic acid reacts with sodium bicarb to form sodium salicylate, which is drinking water soluble are for that reason goes into the h2o layer. Meanwhile, the organic and natural layer now only contains naphthalene, which can be recovered by evaporation of the diethyl ether solvent.
Hope this assists!!!
Sharon asks…
Why does one-butanol has a higher boiling position than diethyl ether?
Why does 1-butanol has a increased boiling level than diethyl ether? Which compound would you assume to be far more soluble in h2o? Why?
ItIsAllHere answers:
1-butanol
OH
|
C-Do-C-Do
diethyl ether
CH3-CH2-O-CH2-CH3
a) * I (believe) the remedy to this lies in the hydrogen bonds from the OH group to other OH teams. It has been a although because I have had Natural and organic Chem.
B) butanol.
Do) the final OH team tends to make the ends far more polar and more soluable in drinking water
Sandy asks…
Why are amines charged in a pH = two answer of diethyl ether and h2o?
Why are amines charged in a pH = 2 solution of diethyl ether and h2o, while alcohols and carboxylic acids are neutral? What establishes if a material will become billed or not in very low or substantial pH? My natural chemistry book does not explain it properly.
ItIsAllHere answers:
Amines, R-NH2, will in acid media pick up a proton to turn into R-NH3+
Acids, nonetheless, are not able to soak up an H+ they release them. So in an acid medium, unless the acid in question is more robust it will not dissociate [a lot - use Ka if you need to get actual].
Alcohols do not typically pick up or discharge ions.
THis ought to have been coated in intro chem, and is assumed as history information in orgo
Donald asks…
Why is methanol far more soluble in h2o than diethyl ether?
Is it just simply because the carbon chain is longer in diethyl ether?or are there other elements also?
ItIsAllHere solutions:
Theres a declaring that goes "like dissolves like".
Water is a polar molecule, that means it will dissolve other polar molecules more very easily. By seeking at the structure of every single you can see that methanol is far more polar than diethyl ether, mostly since of OH team of methanol, in which the hydrogen atom is more effortlessly detached.
