What will be the product formed when acetophenone and acetaldehyde is reacted?

E.g. The aldol reaction of acetaldehyde with acetophenone leads to the formation of 1-phenylbut-2-en-1-one predominantly.

What is the product of aldol condensation of acetophenone?

If we were to form the enolate from ethanal then if this was to attack the carbonyl carbon of acetophenone then we would get a tertary alcohol as the product. The major aldo product in this reaction will be a secondary alcohol formed by the action of the enolate from acetopheone on the ethanal.

How is acetophenone formed?

The compound can be synthesized from benzene and acetyl chloride, but it is prepared commercially by the air oxidation of ethylbenzene.

Does formaldehyde give aldol reaction?

It is the reaction in which two aldehydes or ketones having alpha hydrogen undergo reaction in presence of dilute alkali to form β-hydroxy aldehyde or β-hydroxy ketone. So, there is no alpha hydrogen also. Therefore, formaldehyde cannot undergo aldol condensation.

What is the product of each reaction when acetophenone treated with?

Hence, acetophenone gives ethyl benzene on treating with Zn-Hg/cone.

How many products are formed during the reaction between acetaldehyde and propionaldehyde?

Aldol condensation between acetaldehyde and propanal will possibly give rise to four products.

What is the reaction of acetophenone?

Acetophenone oxime reacts with ethylmagnesium bromide to give the dihydro-1,2-oxazine (118) and this with nitrous acid affords 3,5-diphenyl-6H-1,2-oxazine (119).

Which compound could form directly from the major product of an aldol condensation reaction?

In its usual form, it involves the nucleophilic addition of a ketone enolate to an aldehyde to form a β-hydroxy ketone, or “aldol” (aldehyde + alcohol), a structural unit found in many naturally occurring molecules and pharmaceuticals….

Which reaction is used for the preparation of acetophenone?

Friedel-Crafts reaction
Acetophenone can be prepared by Friedel-Crafts reaction. By treating benzene with acetyl chloride in presence of anhydrous aluminium chloride acetophenone is obtained.

What type of reaction is Cyanohydrin formed from acetone?

The formation of cyanohydrin from acetone is an example of nucleophilic addition.

Why formaldehyde does not give aldol reaction in alkaline medium?

since formaldehyde(i-e HCHO) has only 1 carbon which is the carbonyl carbon (i-e the functional group) and there is no alpha-carbon present and hence no alpha-hydrogen, so formaldehyde doesn’t undergo aldol condensation.

What is produced when acetophenone reacts with Zn Hg?

Zinc amalgum/conc. HCl is an important reducing agent. Hence, acetophenone gives ethyl benzene on treating with Zn-Hg/cone.
