(blank table)
organic naming

1. copy the structural formulas for the following compounds.

methane | (blank box)

Explanation:

1. Oranges: Contain limonene, a cyclic terpene hydrocarbon; functions as a flavor/aroma compound, and has antioxidant properties.
2. Pine trees: Contain pinene, a bicyclic terpene; acts as a defense compound against pests, and contributes to pine scent.
3. Ester #1 (Example: Ethyl acetate): Organic name: ethyl acetate; functional group: ester ($\text{R-COO-R'}$); it is a solvent, and has a fruity (pear-like) aroma.
4. Protein hemoglobin: Function: Transports oxygen from the lungs to body tissues, and carries carbon dioxide back to the lungs for excretion.
5. Glucose (sugar): Organic name: D-glucose; functional group: aldehyde (and multiple hydroxyl groups); it is the primary source of cellular energy for most living organisms.
6. Methane structural formula: The full structural formula shows a central carbon bonded to four hydrogen atoms.

Answer:

1. Oranges: Limonene (cyclic terpene) - flavor/aroma, antioxidant
2. Pine trees: Pinene (bicyclic terpene) - pest defense, pine scent
3. Ester #1 (Ethyl acetate): $\text{CH}_3\text{COOCH}_2\text{CH}_3$ (ester group) - solvent, fruity aroma
4. Protein hemoglobin: Transports $\text{O}_2$ and $\text{CO}_2$ in blood
5. Glucose (sugar): $\text{CH}_2\text{OH(CHOH)}_4\text{CHO}$ - primary cellular energy source
6. Methane structural formula:

$$\begin{array}{c} \quad\quad\text{H}\\ \quad\quad|\\ \text{H}-\text{C}-\text{H}\\ \quad\quad|\\ \quad\quad\text{H} \end{array}$$
