Identify the drug molecule from the skeletal structure shown below.
Show Hint
Memorize the visual shapes from the textbook: Morphine (complex, multi-ring with Nitrogen), Cannabinoid (two main rings, one with -OH, and a long tail), and Cocaine (tropane skeleton).
Step 1: Understanding the Problem:
Psychoactive drugs are classified based on their source and distinct molecular skeletal structures. Key structures typically taught include Morphine (an opioid) and Cannabinoids. Step 2: Approach and Formula:
Identify the class of the psychoactive drug by visually recognizing the characteristic functional groups and ring systems in the chemical skeleton. Step 3: Detailed Explanation:
- Morphine (and other opioids) features a complex, compact polycyclic alkaloid structure that distinctly contains a nitrogen atom in a piperidine ring, along with two hydroxyl (-OH) groups.
- Cannabinoids (such as THC, extracted from {Cannabis sativa}) have a highly distinct structure characterized by a dibenzopyran ring system. Crucially, they lack a nitrogen atom in their core skeletal rings and possess a long, hydrophobic zig-zag hydrocarbon tail (pentyl chain) attached to a phenolic ring.
- The skeletal structure typically presented for this question precisely matches the cannabinoid skeleton, distinctly showing the phenolic -OH group and the long hydrocarbon tail. Step 4: Final Answer:
The given molecule represents a Cannabinoid.
