Question
Chapter 13.9, Problem 13.15P
(a)
Interpretation Introduction
Interpretation:
The chemical shifts of each type of proton are to be determined.
Concept introduction:
The chemical shift is defined as the difference in parts per million in the absorption spectrum of a particular proton from the absorption position of a reference proton. Tetramethylsilane is taken as the reference proton. Chemical shifts are measured in parts per million, and it is dimensionless quantity.
(b)
Interpretation Introduction
Interpretation:
The number of NMR peaks for each type of proton is to be determined.
Concept introduction:
NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is called as a proton in the NMR spectroscopy.
(c)
Interpretation Introduction
Interpretation:
The tree to show the splitting predicted for the absorption of the circled proton is to be drawn.
Concept introduction:
NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is called as a proton in the NMR spectroscopy.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more products missing from the right-hand side, but
there are no reagents missing from the left-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing
from the arrow.
• Is the student's transformation possible? If not, check the box under the drawing area.
• If the student's transformation is possible, then complete the reaction by adding any missing products to the right-hand side, and adding required
catalysts, inorganic reagents, or other important reaction conditions above and below the arrow.
• You do not need to balance the reaction, but be sure every important organic reactant or product is shown.
+
This transformation can't be done in one step.

- Please help me with # 4 and 5. Thanks in advance!arrow_forwardA 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.
