The compounds
Concept Introduction:
Monosaccharides are made from the
Aldohexoses comprise six carbon atoms along with one
Chiral molecules are those molecules that consist of different groups or atoms around the central atom. Optical activity of compounds relies upon the chirality. Only those compounds can rotate light that possess chiral centers.
Isomers are those compounds that have a same molecular formula but the different arrangement of atoms, groups or substituent's in a compound
Aldaric acids are the dicarboxylic acids in which hydroxyl groups are attached to each carbon atom in the compounds.

- 1. Why is "A" the major acetal formed when d-erythrose reacts with H2SO4 and acetone? 2. Why do carbons 2 and 3 on molecule "A" react with H2SO4 and acetone to form acetal "B", rather than carbons 3 and 4 on molecule "A" forming a different acetal?arrow_forwardRing-A is considered a deoxy-pyranoside because it is missing an alcohol functional group on which carbon of ring-A? Use standard carbohydrate numbering. E в он он Oleandrin is a toxic cardiac glycoside found in the poisonous plant, oleander (Nerium oleander L). It has a very long IUPAC name: acetic acid [(35,5R, 10S,13R,14S,16S,17'R)-14-hydroxy-3-[[(2R,4S,5S,6S)-5-hydroxy-4-methoxy-6-methyl- 2-tetrahydropyranyl]oxy]-10,13-dimethyl-17-(5-oxo-2H-furan-3-y)-1,2,3,4,5,6,7,8,9,11,12,15,16,17- tetradecahydrocyclopenta[a]phenanthren-16-yl] ester B.arrow_forwardAll are true or false a)In solution, glucose is in the cyclic acetal form only. b)The driving force for the Wittig reaction is the elimination of triphenylphosphine oxide c)1H NMR spectroscopy, you can tell the difference between an aldehyde and a ketone because an aldehyde has a proton signal between 9–10 ppm. d)When an aldehyde is reacted with excess ethanol with an acid as a catalyst it is called hemiacetal e) You can't use acidic conditions (such as aqueous hydrochloric acid) for the addition of a Grignard reagent to a ketone because the ketone will be protonated and thus unreactivearrow_forward
