What else can I help you with?
What are the example of polar solvent?
Water, alcohols, carbonyls (eg ketones, aldehydes ect), nitriles ect.
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.
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).
What is the colour of semicarbazone of aldehydes?
The semicarbazone derivatives of aldehydes typically appear as yellow to orange crystalline solids. The exact color can vary depending on the specific aldehyde used and its substituents. These compounds are often characterized by their formation through the reaction of aldehydes with semicarbazide in the presence of an acid catalyst.
Carboxylic acid can be prepared by?
Carboxylic acids can be prepared by the oxidation of primary alcohols or aldehydes using oxidizing agents such as chromic acid or potassium permanganate. They can also be obtained by the hydrolysis of nitriles using a strong acid or base. Syndiotactic polymerization of styrene with carbon monoxide can also yield carboxylic acids.
What can lithium aluminum hydride (LiAlH4) reduce?
Lithium aluminum hydride (LiAlH4) can reduce a variety of functional groups in organic chemistry, such as carbonyl compounds (aldehydes, ketones, carboxylic acids, esters), epoxides, and nitriles.
What has the author Thomas Milton Beck written?
Thomas Milton Beck has written: 'The direct auration of aromatic nitriles ..' -- subject(s): Nitriles, Organogold compounds
Are cyanide and nitriles same?
Cyanide and nitriles can be grouped together. A nitrile is an organic compound that contains a cyanide (CN) group. However, other substances often called cyanide are not nitriles, including hydrogen cyanide, sodium cyanide, and potassium cyanide.
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.
Which two groups have the same functional group?
ketones and aldehydes
What are the example of polar solvent?
Water, alcohols, carbonyls (eg ketones, aldehydes ect), nitriles ect.
What homologus series is ethanal in?
Aldehydes

Asymmetric strecker synthesis for clopidogrel?
The asymmetric Strecker synthesis is a method used to prepare chiral α-amino nitriles from aldehydes and primary amines. In the case of clopidogrel, the synthesis involves the formation of the chiral α-amino nitrile, which is subsequently converted into the desired thienopyridine structure through further chemical reactions. The final steps in the synthesis involve the introduction of the clopidogrel-specific moieties to complete the synthesis of clopidogrel.
