The carbonyl group present in aldehydes or ketones itself is optically inactive but if a carbon attached to carbonyl group is asymmetric (attached to four different groups or atoms) then such compound may show to enantiomers as there are two enantiomers of CH3-CHCl-CHO.
Aldehydes and ketones with a chiral center can exhibit optical isomerism. This occurs when the molecule is non-superposable on its mirror image, forming enantiomers. Chiral aldehydes like L and D-glyceraldehyde and ketones like 2-butanol are examples of compounds that display optical isomerism.

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.
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 an organic compound is able to show optical isomerism but not geometrical isomerism?
Optical isomerism arises due to the presence of chiral centers in a molecule, which leads to the molecule being non-superimposable on its mirror image. Geometrical isomerism, on the other hand, arises from restricted rotation around a double bond or ring. Organic compounds can exhibit optical isomerism if they have chiral centers but typically do not show geometrical isomerism unless there are specific structural features like double bonds or rings that limit rotation.
What types of aldehydes and ketones would you expect to be water-soluble?
Small aldehydes and ketones (those with fewer than 5 carbons) are generally water-soluble due to their ability to form hydrogen bonds with water molecules. Examples include formaldehyde (CH2O), acetaldehyde (CH3CHO), acetone (CH3COCH3), and propanal (CH3CH2CHO).
Which two groups have the same functional group?
ketones and aldehydes
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.
What does Clemmensen reduction do to OH group?
Aldehydes and ketones haven't an -OH group.
What are products of ozonolysis of natural rubber?
alcohols, aldehydes or ketones, or carboxylic acids
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.
Are monomers and polymers of aldehydes and keytones that have hydroxyl groups attached?
No, monomers and polymers of aldehydes and ketones do not have hydroxyl groups attached. Aldehydes and ketones have a carbonyl group (C=O) attached to at least one carbon atom and do not have any hydroxyl groups (-OH) attached to the carbon chain.
