Furman Chemistry 120: Organic / Enolate Anion Stability

Methyl acetate has a pKa of 25 which may be surprising if one assumes that the greater electronegativity of oxygen would make the ester enolate anion more stable than that of a ketone Similarly the greater electronegativity of nitrogen in N N-dimethylacetamide (pKa 30) should make this compound more acidic than acetone right? Actually oxygen or nitrogen can influence acidity by an

ACIDS AND BASES IN ORGANIC CHEMISTRY

If we consider the reaction of acetate ion with ethanol the products would be acetic acid and ethoxide ion On the left we have ethanol as the B-L acid and on the right acetic acid From its lower pK value we know that acetic acid is the stronger acid so it will be converted primarily to the weaker acid which is ethanol Thus as written the reaction proceeds to the left That is as

pka of methyl acetate

Methyl acetate also known as MeOAc acetic acid methyl ester or methyl ethanoate is a carboxylate ester with the formula CH 3 COOCH 3 It is a flammable liquid with a characteristically pleasant smell reminiscent of some glues and nail polish removers Methyl acetate is occasionally used as a solvent being weakly polar and lipophilic but its close relative ethyl acetate is a more common

Ethyl acetate

Ethyl acetate (systematically ethyl ethanoate commonly abbreviated EtOAc ETAC or EA) is the organic compound with the formula CH 3 −COO−CH 2 −CH 3 simplified to C 4 H 8 O 2 This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues nail polish removers and in the decaffeination process of tea and coffee Ethyl acetate is the ester of ethanol

What Are the Dangers of Sodium Acetate?

Sodium acetate is potentially flammable and should not be brought in contact with open flames 2 3 It reacts violently with some strong oxidants and strong acids like nitric acid or potassium nitrate Under the right conditions a mixture of potassium nitrate and sodium acetate will explode so sodium acetate must be stored separately from potassium nitrate and other strong oxidants 2 3 The

Determination of the pKa of Ethyl Acetate: Brnsted

The rate constants for deprotonation of ethyl acetate by 3-substituted quinuclidines are correlated by β = 1 09 0 05 The limits of kBH = 2−5 109 M-1 s-1 for the encounter-limited reaction of the simple oxygen ester enolate with protonated quinuclidine (pKBH = 11 5) were combined with kB = 2 4 10-5 M-1 s-1 for deprotonation of ethyl acetate by quinuclidine to give pKaK = 25 6 0

Methyl acetate

Methyl acetate could not be detected in any sample whereas methanol was found in blood and urine already after 30 min Peak concentrations of methanol in the blood were measured after 3 hours and amounted to 0 573 mg/mL Following oral application methyl acetate is hydrolysed in the gut Therefore in blood and urine only methanol and acetic acid were found not methyl acetate Similarly

Amine Basicity Is Measued By The pKa Of Its Conjugate

The value of 10 63 actually refers to the pKa of the conjugate acid of methyl amine NOT methylamine itself It's a pKaH value Similarly the same table lists trimethylamine as having a pKa of 9 8 Again this is actually its pKaH I can't find an actual pKa value for trimethylamine but I would guess that it is 40 since the conjugate base of trimethylamine is the carbanion (CH
