You can tell that spacing is a problem on this forum.
To identify the image(s) that exhibit the opposite chirality, we need to compare the orientation of the substituents around the chiral center. The chiral center in this case is the carbon atom bonded to the chlorine atom (CI).
In the given structure, CI is connected to three groups - H, COOH, and CH3. The chirality of the structure is determined by the spatial arrangement of these groups around the chiral center.
To determine the opposite chirality, we need to look for structures where the spatial arrangement of the substituents is flipped or mirror-imaged compared to the given structure.
Let's analyze each image:
(a) The given structure (COOH) is the same as the original structure. It does not exhibit the opposite chirality.
(b) In this structure (H), compared to the original structure, the H and CI groups are flipped, but the COOH group remains the same. It does not exhibit the opposite chirality.
(c) In this structure (CI), compared to the original structure, the H and COOH groups are flipped, but the CH3 group remains the same. It exhibits the opposite chirality.
(d) The given structure (COOH) is the same as the original structure. It does not exhibit the opposite chirality.
Therefore, the image that exhibits the opposite chirality is (c) CI.
