Are ketones acidic in nature?
Yes, ketones are slightly acidic in nature.
Why are ketones acidic in nature?
Ketones are acidic in nature because they contain a carbonyl group, which can release a hydrogen ion (H) in a chemical reaction, making them acidic.
The presence of ketones changed the pH in the urine of the patient. The pH of the urine was?
The presence of ketones in urine can lead to a decrease in pH, making it more acidic. This change in pH is due to the acidic nature of ketones, such as beta-hydroxybutyric acid, which are produced during fat metabolism. Hence, a lower pH in the urine of the patient is likely.
What is the difference in acidity between aldehydes and ketones?
Aldehydes are generally more acidic than ketones due to the presence of a hydrogen atom attached to the carbonyl group in aldehydes, which can be easily donated as a proton. This makes aldehydes more reactive towards nucleophiles compared to ketones.
Can high levels of ketones in the blood lead to high pH of urine?
Yes, high levels of ketones in the blood can lead to an increase in urine pH. Ketones are acidic compounds, so as the body tries to eliminate them through urine, it can lead to a higher pH in the urine. This can be a sign of a metabolic imbalance such as diabetic ketoacidosis.

Are ketones basic?
I think ketones are slightly basic due to the resonance of the doule bond in the carbonyl functional group. This will leave a negative charge on the oxygen making it capable of acting as a weak Lewis base.
What is the difference in acidity between aldehydes and ketones?
Aldehydes are generally more acidic than ketones due to the presence of a hydrogen atom attached to the carbonyl group in aldehydes, which can be easily donated as a proton. This makes aldehydes more reactive towards nucleophiles compared to ketones.
Why KCN fail to react with aldehyde and ketones?
KCN does not react with aldehydes and ketones because these compounds do not have an acidic hydrogen that can be removed to form an enolate ion, which is necessary for nucleophilic addition reactions with cyanide ions. Aldehydes and ketones lack the necessary alpha carbon acidity to undergo this reaction with KCN.
Can high levels of ketones in the blood lead to high pH of urine?
Yes, high levels of ketones in the blood can lead to an increase in urine pH. Ketones are acidic compounds, so as the body tries to eliminate them through urine, it can lead to a higher pH in the urine. This can be a sign of a metabolic imbalance such as diabetic ketoacidosis.
Why are ketone pathological conditions associated with vomiting?
Activation of chemoreceptors in the Medulla. Possibly due to the acidic nature of Ketones, this would have an effect on the vomiting centres in the brain.
Why is the pka of fluorenone different that other ketones?
9-fluorenone is different because it is a ketone with all of its carbons tied up in double bonds. There are no readily available acidic hydrogens, therefore this makes the pka of the molecule much greater than most other ketones.
Why are ketones more reactive towards nucleophiles than esters?
Ketones have a more electrophilic carbonyl carbon compared to esters because they lack the electron-donating groups present in esters. This makes ketones more susceptible to nucleophilic attack. Additionally, the steric hindrance around the carbonyl carbon in esters can reduce the reactivity towards nucleophiles compared to ketones.
Why only methyl ketones give iodoform test?
Methyl ketones like acetone can undergo oxidation reaction with iodine and sodium hydroxide to form iodoform due to the presence of the methyl group (-CH3). The reaction involves the formation of a carboxylate ion intermediate that contains an acidic hydrogen atom on the methyl group, which leads to the production of iodoform. Other ketones lacking the methyl group do not undergo this reaction.
Can sodium borohydride reduce ketones?
Yes, sodium borohydride can reduce ketones.
