What happens when acetophenone reacts with phenylhydrazine?
Here phenylhydrazine condenses with acetophenone to produce acetophenone phenylhydrazone. Finally by Fischer indole synthesis the arylhydrazone (acetophenone phenylhydrazone) converts into the indole (2-phenylindole) in the presence of an acid catalyst. Aim: To prepare 2-phenylindole from phenyl hydrazine.
What functional group would you find in acetophenone?
ketone functional group
Acetophenone contains both benzene and a ketone functional group.
What is the structure of phenylhydrazone Class 12?
Phenylhydrazine | C6H5NHNH2 – PubChem.
When hydrazine reacts with ketone The product is?
Hydrazine, organohydrazines, and 1,1-diorganohydrazines react with aldehydes and ketones to give hydrazones.
Is acetophenone polar or nonpolar?
The structure of acetophenone is shown below: Due to the presence of a polar carbonyl group, acetophenone possesses a dipole moment, which…
Is benzoic acid or acetophenone more polar?
This can be explained because the structures of the molecules with an – OH group are more polar. Phenol and Benzoic Acid were listed as polar, Acetophenone and Phenyl Acetate as somewhat polar, and Anisole as non-polar.
Is acetophenone soluble in water?
Pure acetophenone is a colourless liquid, with a melting point of 20.2 °C (68.4 °F) and a boiling point of 202.4 °C (396.3 °F). It is only slightly soluble in water but is freely soluble in ethanol (ethyl alcohol), diethyl ether, and chloroform.
What’s the structure of acetophenone?
Acetophenone is the organic compound with the formula C6H5C(O)CH3 (also represented by the pseudoelement symbols PhAc or BzMe). It is the simplest aromatic ketone. This colorless, viscous liquid is a precursor to useful resins and fragrances.
What is the molar mass of acetophenone?
120.15 g/molAcetophenone / Molar mass
How is phenylhydrazone formed?
The condensation between phenylhydrazine and a carbonyl compound (aldehyde or ketone) to form phenylhydrazone and the compounds condensed from carbohydrates and 2 eq of phenylhydrazine are generally known as osazones or specifically referred to as glycosazones.

When compound a ketone is react with hydrazine it gives dimethylhydrazine as a product which is the compound a MCQ?
Expert-verified answer Dimethyl hydrazine has two methyl groups. It means the reactant ketone should also have only two methyl groups attached to the carbonyl carbon. Out of the given options, only acetone has two methyl groups attached to the carbonyl carbon. Hence, option C (Acetone) would be correct.
What type of reaction takes place upon treatment of a ketone with hydrazine to form an hydrazone?
Aldehydes and ketones can be converted to a hydrazone derivative by reaction with hydrazine (H2NNH2). Hydrazone formation is a variation of the imine forming reaction discussed in the previous section.
Why is acetophenone not soluble in water?
Acetone is completely miscible in water while acetophenone does not. Acetone is miscible in water as it is capable of forming H-bond with water. But due to bulky benzene ring, acetophenone cannot form hydrogen bonds with H2O, hence it is immiscible.
Is acetophenone polar?
Is acetophenone more polar than 1 Phenylethanol?
Acetophenone is a ketone. When comparing the two structures one can observe that 2 -phenylethanol is more polar than acetophenone. Therefore, one need a moderately polar solvent to effectively separate these two components in a mixture.
What is structure of phenylhydrazone?
C6H8N2Phenylhydrazine / Formula
What happens when ketone reacts with hydrazine?
Aldehydes and ketones can be converted to a hydrazine derivative by reaction with hydrazine. These “hydrazones” can be further converted to the corresponding alkane by reaction with base and heat.
