The structure of fructose in both its forms, open and closed-chain, is to be drawn. Concept Introduction: Carbohydrates are polyhydroxy aldehydes or ketones , or their derivatives. Carbohydrates can be categorized as monosaccharides, disaccharides, and polysaccharides. Monosaccharides are composed of a single sugar unit. Disaccharides are double-ringed structures in which two monosaccharide units are linked together. Polysaccharides are long chains of monosaccharide units. They are also called complex carbohydrates.

Question

Part II. Given two isomers: 2-methylpentane (A) and 2,2-dimethyl butane (B) answer the following: (a) match structures of isomers given their mass spectra below (spectra A and spectra B) (b) Draw the fragments given the following prominent peaks from each spectrum: Spectra A m/2 =43 and 1/2-57 spectra B m/2 = 43 (c) why is 1/2=57 peak in spectrum A more intense compared to the same peak in spectrum B.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
