Interpretation:
To accurately depict the given ball-stick model, the dash-wedge notations in the given line structure are to be added.
Concept introduction:
The dash-wedge notations are used to represent the three-dimensional arrangement of atoms or groups of molecules in plane of paper. There are three types of lines used for such arrangements, straight line, dash line, and wedge line. The straight line represents the bond is in the plane of the paper. The dash line represents the bond pointing away from the observer, that is, below the plane of paper. The wedge line represents the bond pointing towards the observer that is above the plane of paper.

The dash-wedge notations in the given line structure is:
Explanation of Solution
The given ball-stick model and the line structure are:
In the given ball-stick model, the yellow balls represent fluorine atoms and black balls are carbon atoms. The fluorine atoms on the left side appear in the plane of the paper. Thus, these fluorine atoms will be represented by straight lines. The two fluorine atoms on the right side are arranged such that, one fluorine atom is above the plane of paper and other is below. The one which is above the plane will be represented by a wedge bond while the one which is below the plane of the paper will be represented by a dash line.
Hence dash-wedge notation for the given molecules is shown below:
The dash-wedge notation in the given line structure is added on the basis of three dimensional arrangement given in ball-stick model.

The dash-wedge notations in the given line structure is:
Explanation of Solution
The given ball-stick model and its line structure are:
In the given ball-stick model the white balls represent hydrogen atoms, black balls represents carbon atoms and the red ball is an oxygen atom. The two carbon atoms that are directly bonded to the oxygen atom are in the plane of paper. Each of these carbon atoms has one methyl substituent and one hydrogen atom attached. Two methyl substituents points towards the observer, while the hydrogen atoms are pointing away from the observer. The bond towards the observer is considered as above the plane of the paper and is represented by wedge bond. The bond away from the observer is considered as below the plane of the paper and is represented by dash bond.

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.
