This reaction involves the following intermediate steps: 1. Addition of phenylhydrazine to the imine and proton transfer to yield intermediate 1; 2. Elimination of ammonia to yield phenylhydrazone 2; 3. Addition of phenylhydrazine to the ketone to yield tetrahedral intermediate 3; 4. Proton transfer yields carbinolamine 4; 5.

Raffinose doesnot reduce Tollens reagent, and it does not mutarotate. Complete hydrolysis of raffinosegives d-glucose, d-fructose, and d-galactose. When raffinose is treated with invertase,the products are d-fructose and a reducing disaccharide called melibiose. Raffinose isunaffected by treatment with a b@galactosidase, but an a@galactosidase hydrolyzes itto d-galactose and sucrose. When raffinose is treated with dimethyl sulfate and basefollowed by hydrolysis, the products are 2,3,4-tri-O-methylglucose, 1,3,4,6-tetraO-methylfructose, and 2,3,4,6-tetra-O-methylgalactose. Determine the completestructures of raffinose and melibiose, and give a systematic name for melibiose.arrow_forward
