What happens when D glucose is treated with sodium borohydride?
When D-glucose is treated with sodium borohydride, optically active glucitol results. When optically active D-galactose is reduced, however, the product is optically inactive.
Is sodium borohydride oxidized?
Oxidation. Oxidation with iodine in tetrahydrofuran gives borane–tetrahydrofuran, which can reduce carboxylic acids. Partial oxidation of borohydride with iodine gives octahydrotriborate: 3 BH4− + I2 → B3H8− + 2 H2 + 2 I.
What is the product of NaBH4 and HCl?
equation for the reaction that occurs is H:θ (from NaBH4) + H⊕ (from HCl) → H2 (gas). Because this is an acid-base reaction, heat is liberated and the reaction mixture becomes slightly warm.
What is the formula of sodium borohydride?
NaBH4Sodium borohydride / Formula
What is the major product of this reaction NaBH4 MeOH?
Thus, the reduction of the ketone to alcohol took place by the sodium borohydride in MeOH solvent. Therefore, the major product formed from the reduction of the given compound is option (B) 2-Bromo-1-phenyl-ethanol. Note: The NaBH4 is a very selective reducing agent.
Which method used to ascent the series of aldehyde in carbohydrates?
Answer. Answer: The Kiliani–Fischer synthesis, named for German chemists Heinrich Kiliani and Hermann Emil Fischer, is a method for synthesizing monosaccharides.
When a carbohydrate reacts with alcohol What is the product?
Aldehydes, i.e. aldoses, are reduced to primary alcohols. Ketones, i.e. ketoses, are reduced to secondary alcohols.
What is the product of baeyer Villeger reaction?
The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant….Baeyer–Villiger oxidation.

How does sodium borohydride decompose?
Sodium borohydride is a white to grayish crystalline powder. It is decomposed by water to form sodium hydroxide, a corrosive material, and hydrogen, a flammable gas. The heat of this reaction may be sufficient to ignite the hydrogen. The material itself is easily ignited and burns vigorously once ignited.
What is the scientific name for NaBr?
Sodium bromide (NaBr)
