The concept of constitutional isomerism and acidic nature of the given set of compounds should be identified. Concept introduction: Acidity: Acidity of the compound is the measure of strength of the acid. If the acid forms a more stable conjugate base after deprotonation then that acid is said to be more acidic. The number and the strength of electron withdrawing group attached to the carbon that bears the removable proton determine the acidity of compound. Isomer : “Compounds whose molecular formula is same but the arrangement of atoms are different in their molecule and they differ in chemical structure. They distinct in chemical and physical properties also” Types : Isomerism are classified into two types 1. Constitutional or Structural isomerism 2. Stereo or Spatial isomerism Constitutional or Structural isomerism : Compounds which have same molecular formula are having different connectivity of atoms and with different structure. These isomers can also be referred as “structural isomers”. Structural isomers have different IUPAC names.

Interpretation Introduction

Interpretation:

The concept of constitutional isomerism and acidic nature of the given set of compounds should be identified.

Concept introduction:

Acidity:

Acidity of the compound is the measure of strength of the acid. If the acid forms a more stable conjugate base after deprotonation then that acid is said to be more acidic. The number and the strength of electron withdrawing group attached to the carbon that bears the removable proton determine the acidity of compound.

Isomer:

“Compounds whose molecular formula is same but the arrangement of atoms are different in their molecule and they differ in chemical structure. They distinct in chemical and physical properties also”

Types:

Isomerism are classified into two types

1. Constitutional or Structural isomerism

2. Stereo or Spatial isomerism

Constitutional or Structural isomerism:

Compounds which have same molecular formula are having different connectivity of atoms and with different structure. These isomers can also be referred as “structural isomers”. Structural isomers have different IUPAC names.

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.…
