Does ethanoic acid more closely resemble hydroxyl or carbonyl compounds in its reaction?
Ethanoic acid resembles hydroxyl compounds more than carbonyl because it reacts with sodium and phosphorus pentachloride, typical alcohol reactions. But it doesn't react with 2,4- dinitrophenylhydrozine (typical carbonyl compound).
Does carbonyl act as an acid or a base?
A carbonyl group can act as both an acid and a base. In acidic conditions, it can donate a proton from the oxygen atom, functioning as an acid. In basic conditions, it can accept a proton on the oxygen atom, acting as a base.
Why is ethanoic acid insoluble in water?
Ethanoic acid (acetic acid) is soluble in water because it can form hydrogen bonds with water molecules, allowing it to dissolve. Ethanoic acid is a polar molecule due to its carbonyl group, allowing it to interact with the polar water molecules.
What is the central atom in the amino acid?
the carbon in carbonyl function
What is the function of sulfuric acid in the esterification reaction?
Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
What is the ternary acid HIO4?
HIO4 is known as periodic acid. It is a strong oxidizing agent and is used in organic chemistry for reactions involving oxidation of alcohols to carbonyl compounds. Periodic acid is a colorless solid and is highly soluble in water.
Explain why the carbonyl oxygen in the acid-base protonation reaction of acetic acid preferentially gets protonated over the hydroxyl group in the acetic acid?
The carbonyl oxygen is more acidic than the hydroxyl group in acetic acid because the carbonyl oxygen is part of a more stable conjugate base. The resulting carboxylate anion is resonance stabilized due to delocalization of the negative charge over the two oxygen atoms. This makes it easier for the carbonyl oxygen to accept a proton.
An unknown carbonyl compound tested positive when mixed with chromic acid solution it also showed positive results in the iodoform test draw the struture of this compound?
The unknown carbonyl compound is likely a methyl ketone. When reacted with chromic acid, it undergoes oxidation to form a carboxylic acid. In the iodoform test, it forms a yellow precipitate of iodoform (CHI3) due to the presence of a methyl group adjacent to the carbonyl carbon.
Does ethanoic acid is more soluble than hexanoic acid in water?
Yes, ethanoic acid (acetic acid) is more soluble in water than hexanoic acid. This is because ethanoic acid is a smaller molecule with a polar carbonyl group, allowing it to form hydrogen bonds with water molecules more easily compared to hexanoic acid.
Which is the enzyme which catalyses the reaction of glucose to gluconic acid?
Glucose oxidase that converts the carbonyl (aldehyde) carbon of glucose to a carboxylic acid.
What are the acidic hydrogens in salicylic acid?
The OH group bonding with the carbonyl group has a pKa around 5, and the OH group connected ortho of the carbonyl group has a pKa around 10. Added correction: Salicylic acid is a monoprotic, not a diprotic acid in water. From wikipedia table value: pKa 2.97
When a carboxylic acid and an amine react they form a?
When a carboxylic acid and an amine react, they form an amide through a condensation reaction. This reaction involves the loss of a water molecule and the formation of a new C-N bond between the carbonyl carbon of the carboxylic acid and the amino nitrogen of the amine.
