It should be drawn the mechanism for the racemization process in aqueous acid. Concept introduction: Aldol addition reaction means the reaction between aldehyde which has an α hydrogen to form an addition product comprising of aldehyde and alcohol group in presence of base, namely sodium hydroxide. The name Aldol stands for aldehyde and alcohol (ald for “aldehyde” and ol for “alcohol”). The three steps involved in aldol addition reaction is, Deprotonation of α carbon Attach of enolate ion with the aldehyde (nucleophilic attack) Protonation of the alkoxide ion to give aldol product Oxidation of an alcohol with PCC to give an aldehyde means the alcohol has to be primary alcohol.

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.

A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…
