Question

identify all carbon chiral centers in coniine, nicotine, and cocaine.

Short answer

Question: Identify the number of chiral centers in coniine, nicotine, and cocaine. Answer: Coniine has 1 chiral center, nicotine has 2 chiral centers, and cocaine has 1 chiral center.

Step-by-step solution

Identify the molecular structure of coniine, nicotine, and cocaine

To identify the molecular structure of coniine, nicotine, and cocaine, we can use available resources like textbooks, online databases, or search engines. The molecular structures for these compounds are as follows: - Coniine: C8H17N - Nicotine: C10H14N2 - Cocaine: C17H21NO4

Identify chiral centers in coniine

Coniine's molecular structure is shown below: ``` CH3-CH-N-CH2-CH2-CH2-CH2-CH3 | CH3 ``` There is only one chiral carbon in coniine's structure, which is the carbon that is adjacent to the nitrogen atom: ``` * CH3-CH-N-CH2-CH2-CH2-CH2-CH3 | CH3 ```

Identify chiral centers in nicotine

Nicotine's molecular structure is shown below: ``` H NCH3 |\ | H-C-CH-C || | N CH3 | CH \ CH2 / CH | CH3 ``` There are 2 chiral carbons in nicotine's structure: one connecting to the pyrrolidine ring and the other connecting to the pyridine ring: ``` H *NCH3 |\ | H-C-CH-C *| | N CH3 | CH \ CH2 / CH | CH3 ```

Identify chiral centers in cocaine

Cocaine's molecular structure is shown below: ``` H O O |\ // || H-C-C6H4-CO-C-CH3 || | // N CH3 O | CH2 || OCH3 ``` There is only one chiral carbon in cocaine's structure, which is the carbon that is adjacent to the nitrogen atom and aromatic ring: ``` H O O |\ // || H*C-C6H4-CO-C-CH3 || | // N CH3 O | CH2 || OCH3 ```

Summarize the results

- Coniine has 1 chiral center. - Nicotine has 2 chiral centers. - Cocaine has 1 chiral center.
