(a)
Interpretation:
The products obtained from the reaction of lactobionic acid and
Concept introduction:
The hydrolysis of the disaccharides is done in the presence of acid as a catalyst. The hydrolysis of the disaccharide is the breaking of the glycosidic linkage to give two monosaccharides units. Glycosidic linkage is an acetal linkage and acetal linkage hydrolysis takes place in the presence of an acidic solution.
(b)
Interpretation:
The products obtained from the reaction
Concept introduction:
The methylation of the hydroxyl group of sugars is an important reaction. The methylation of hydroxyl groups is done with the help of methylating agent, dimethyl sulfate in the presence of strong base sodium hydroxide.
(c)
Interpretation:
The products obtained from the reaction product of part (b) and
Concept introduction:
The hydrolysis of the disaccharides is done in the presence of acid as a catalyst. The hydrolysis of the disaccharide is the breaking of the glycosidic linkage to give two monosaccharides units. Glycosidic linkage is an acetal linkage and acetal linkage hydrolysis takes place in the presence of an acidic solution.

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
