AIIMS 2019 Chemistry Structure Determination MCQ Question

Option A is correct because it accurately represents the molecular structure of the compound in question, displaying the correct arrangement of atoms and functional groups, which is essential for understanding its chemical behavior. The other options are incorrect as they either misrepresent the connectivity of atoms or fail to include critical functional groups, leading to discrepancies in predicted reactivity and properties. For instance, option B lacks the necessary hydroxyl (-OH) group, while option C incorrectly depicts a double bond that does not exist in the compound. Understanding the precise structure is crucial for predicting the compound's interactions and reactivity in biological systems.
