Is schiff base is prepared by mannich reaction?
No, Schiff base is not prepared by Mannich reaction. Schiff base is typically formed through the condensation reaction between a primary amine and a carbonyl compound. Mannich reaction, on the other hand, involves the condensation of a primary or secondary amine, a carbonyl compound, and formaldehyde or a derivative.
Why glucose is used for the preparation of schiff base?
Glucose is used for the preparation of Schiff base because it contains multiple hydroxyl groups that can react with an aldehyde or ketone to form a Schiff base. The reaction between glucose and the carbonyl compound leads to the formation of a stable imine or Schiff base linkage.
What is the mechanism of schiff base formation?
Schiff base formation involves the nucleophilic addition of a primary amine to a carbonyl group (aldehyde or ketone), resulting in the formation of an imine intermediate. The imine intermediate then undergoes a proton transfer to form the final Schiff base compound, which is characterized by a C=N bond. This reaction is reversible and can be catalyzed by acid or base.
Equation of formaldehyde schiff's reagent benzaldehyde schiff's reagent and acetone schiff's reagent?
Formaldehyde Schiff's reagent: It is a solution of formaldehyde and sulfuric acid, used to detect the presence of aldehydes. The equation involves the formation of a colored compound with aldehydes. Benzaldehyde Schiff's reagent: Benzaldehyde can act as a Schiff's base with primary amines to form imines. The reaction results in the formation of a colored compound. Acetone Schiff's reagent: Acetone can react with a primary amine to form a Schiff's base, leading to the formation of a colored compound.
How can you synthesise a schiff base from camphor and amine?
Reaction of camphor with an aromatic amine can be achieved using 10% zinc chloride as a catalyst in a suitable organic solvent under reflux conditions.See "Preparation and reduction of camphor imines" - Bolton, Danks & Paul. Dept of Chem, University of Surrey, 1994.The abstract of the paper does not identify which solvent is used, reflux time or product yield.

Why schiff base is so called?
hi, schiff base is so called because Hugo schiff was discover it

How schiff's base was discovered?
Schiff base was proposed by Hugo Schiff and are imines that are formed by the condensation of aldehydes or ketones with primary amines.

What is the general reaction equation of schiff's test?
In Schiff's test, aldehydes react with a fuchsin sulfurous acid solution to form a pink to magenta color complex. The general reaction equation involves the aldehyde group (-CHO) in the compound oxidizing the sulfur dioxide to form the colored complex, which can be represented as: RCHO + H2SO3 -> Colored Schiff's base compound

What will be the mobile phase for Thin Layer Chromatography of Schiff base?
Schiff bases are imines formed by the condensation of aldehydes or ketones with primary amines. The mobile phase for this could be ethyl acetate in hexane or chloroform in methanol.
What are the conditions for the neutralisation reaction?
N1*V1 = N2*V2 (where N1 & N2 are the normality of respective acid or base while V1 & V2 is their respective volume).
