Thestructure of the product formed by reaction of aniline with each of the given reagent is to be predicted. Concept introduction: The aryl amines are weak bases that can abstract proton from a strong acid and form their conjugate acids. The primary amine, on reaction with excess of primary alkyl halide , undergoes nucleophilic substitution and forms quaternary ammonium salt. The primary amine can be converted to an amide by the reaction with acyl chloride or acid anhydride. The nucleophilic addition of primary amine to the carbonyl group of aldehyde or ketone forms an imine. The imine, on catalytic hydrogenation, forms a secondary amine. The aryl diazonium salt is a key intermediate in synthesis of aromatic compounds , which is prepared by nitrosation of amine (primary aryl amine) by sodium nitrite in acidic condition.

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.…
