The Haworth projection formula of the disaccharides maltose and sucrose is to be drawn. The hemiacetal, hemiketal, acetal or ketal carbons are to be labeled. Concept introduction: Monosaccharides are the small units of simple sugars. Polysaccharides are made up of small units of monosaccharides. The carbohydrates with free aldehyde or ketone groups can act as reducing sugars. Under basic conditions, weak oxidizing agents such as Tollen’s reagent and Benedict’s solution oxidize the aldehyde or ketone group of the monosaccharide.

Question

Consider a solution of 0.00304 moles of 4-nitrobenzoic acid (pKa = 3.442) dissolved in 25 mL water and titrated with 0.0991 M NaOH. Calculate the pH at the equivalence point

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.
