The mechanism for the reaction between Grignard reagent and oxetane to produce primary alcohol is to be proposed and the reason corresponding to the fact that oxetane reacts with Grignard reagent even though most ethers do not is to be stated. Concept introduction: The reaction of metals like lithium and magnesium with vinyl halides, alkyl halides and aryl halides gives organometallic compound as a product. The compounds in which carbonyl groups are present like ketone or aldehyde react with Grignard reagent to form alcohol. The examples of Grignard reagent are ethyl magnesium bromide and PhMgBr . Ether is used as the solvent in the Grignard reactions. To determine: The mechanism for the reaction between Grignard reagent and oxetane to produce primary alcohol and the reason corresponding to the fact that oxetane reacts with Grignard reagent even though most ethers do not.

Question

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.…
