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.

Difference between aromatic and aliphatic aldehyde?
Aromatic aldehydes contain an aromatic ring in their structure, while aliphatic aldehydes have a straight or branched carbon chain. Aromatic aldehydes typically have a stronger smell compared to aliphatic aldehydes due to their benzene ring. Aromatic aldehydes are commonly found in natural sources like plants, while aliphatic aldehydes are more often associated with industrial processes.
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.
How are ketone and aldehydes related?
Aldehydes and ketones contain the carbonyl group C=O.
Which two groups have the same functional group?
ketones and aldehydes
What kind of alcohols can be used to prepare aldehydes?
Primary alcohols can be oxidized to aldehydes using mild oxidizing agents such as PCC (pyridinium chlorochromate) or PDC (pyridinium dichromate). Examples of primary alcohols that can be used include ethanol, propanol, and butanol.

What homologus series is ethanal in?
Aldehydes
How will you characterize the rate of reaction of an aldehyde compared to an aliphatic aldehyde?
Typically aromatic groups attached to functional groups increase the reaction over that of an aliphatic groups. Aromatic aldehydes (e.g. benzaldehyde, C6H5.CHO), are also known which undergo a number of chemical reaction which do nor occur for aliphatic aldehydes and which are unique to aromatic aldehydes.
Which aldehyde do not give fhelings test?
Aromatic aldehydes, such as benzaldehyde, typically do not give a positive Fehling's test due to the lack of alpha-hydrogens required for oxidation. Aromatic aldehydes are not easily oxidized in the Fehling's test compared to aliphatic aldehydes.
Polyhydroxy derivatives of aldehydes or ketoens are?
Carbohydrates
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).
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.

What is aldehydes in PAS stain?
Aldehydes are what create the color in any stain; especially the PAS stain. In reference, the aldehyde are the pigments that can cause permanent staining in a fabric.
