Why is ketones and aldehydes are called as polar compounds?

aldehydes n ketones contain a carbonyl group in which carbon is attached to an oxygen with a double bond. The carbon is less electronegative than oxygen therefore carbon acts as an electrophile and oxygen acts an a nucleophile. That is carbon is partially positively charged n oxygen is partially negatively charged. Hence aldehydes n ketones are polar compounds


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 are four classes of organic compounds found in all living things?

Lipids, Carbohydrates, Proteins, Nucleic acids


What does Clemmensen reduction do to OH group?

Aldehydes and ketones haven't an -OH group.


What class of molecules contain the carbonyl group CO?

There are many. Aldehydes, ketones, carboxylic acids, amides, esters, acid anhydrides and organo-metallic compounds such as Iron Pentacarbonyl etc contain the -C=O group.


Is CHO an organic compound?

CHO is the functional group for aldehydes.


What element do amines contain that aldehydes and alcohol do not?

It is Nitrogen, located in the amino-group ( -NH2)


What is the telltale functional group that distinguishes an alcohol molecule?

Optical isomerism in aldehydes and ketones?

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.


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.


What contains the carbony1 group?

A carbonyl is a C double bonded to an oxygen. One can find these in aldehydes, ketones, and carboxylic acids.
