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.

What is the difference between aldehydes and ketones?

Aldehydes and ketones are both types of organic compounds with a carbonyl group, but the key difference is their location within the molecule. Aldehydes have the carbonyl group at the end of a carbon chain, while ketones have it in the middle. This structural variance leads to differences in their chemical properties and reactivity.


What are the key differences between the aldehyde and ketone functional groups?

The key difference between aldehydes and ketones is the location of the carbonyl group. In aldehydes, the carbonyl group is located at the end of the carbon chain, while in ketones, it is located within the carbon chain. This difference affects their chemical properties and reactivity.


How areketones and aldehydes related?

Ketones and aldehydes are both organic compounds that contain a carbonyl functional group (C=O). The main difference between them is in the placement of the carbonyl group: ketones have the carbonyl group located in the middle of the carbon chain, while aldehydes have it at the end of the chain. Both ketones and aldehydes are important in various chemical reactions and serve as building blocks for more complex molecules.


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.


Which two groups have the same functional group?

ketones and aldehydes


How are ketone and aldehydes related?

Aldehydes and ketones contain the carbonyl group C=O.


What is the mechanism of the Tollens test and how does it differentiate between aldehydes and ketones?

The Tollens test involves the oxidation of aldehydes to carboxylic acids by silver ions in a basic solution. This forms a silver mirror on the inside of the test tube. Ketones do not react with Tollens reagent and do not produce a silver mirror. This test is used to differentiate between aldehydes and ketones based on their reactivity with Tollens reagent.


What are the formulas of aldehydes and ketones?

The general formula for aldehydes is RCHO (where R is a hydrocarbon group), and the general formula for ketones is R2CO (where R is a hydrocarbon group).


From an organic chemistry perspective carbohydrates are polyhydroxyl?

Aldehydes and ketones


Why are aldehydes more reactive than ketones towards nucleophile?

Aldehydes are less sterically hindered than ketones. Also, aldehydes have fewer electron donating groups (EDG's) which can stabilize an electron-poor area. The extra carbon chain that ketones have that aldehydes do not have are the reason for both of these things. The neighboring carbon to the carbonyl carbon is an EDG and the carbon chain causes steric hindrance.


How does ketones react with sodium bicarbonate?

Ketones or Aldehydes DO NOT react with Sodium Bicarbonate..generally only Carboxilic acids have the ability to do it!


Tollen's test on ketones?

A Silver mirror does not appear as ketones cannot be further oxidized unlike aldehydes in which a silver mirror does appear.
