oranges
pine trees
ester #1 (choose one from list)
protein hemoglobin function:
glucose (sugar)

1. hydrocarbon uses

organic naming

1. copy the structural formulas for the following compounds.

methane

Explanation:

Step1: Fill Oranges entry

Organic name: Ascorbic acid (vitamin C); Function: Antioxidant, supports immune function, collagen synthesis

Step2: Fill Pine trees entry

Organic name: Pinene (alpha-pinene, beta-pinene); Function: Defense against pests, contributes to pine scent, used in solvents/aromatics

Step3: Fill Ester #1 example (Ethyl acetate)

Organic name: Ethyl acetate; Function: Solvent for paints, adhesives, flavoring agent

Step4: Fill Hemoglobin function

Function: Transports oxygen from lungs to body tissues, carries carbon dioxide back to lungs

Step5: Fill Glucose entry

Organic name: D-glucose; Function: Primary cellular energy source, metabolic fuel for organisms

Step6: Hydrocarbon Uses example entries

Hydrocarbon	Common Use
Propane	Fuel for grills, heating
Octane	Gasoline additive for engine performance

Step7: Draw Methane structural formula

Methane structural formula:

      H
      |
H — C — H
      |
      H

Or in condensed structural form: $\text{CH}_4$ (displayed as a tetrahedral structure with carbon at the center bonded to 4 hydrogen atoms)

Answer:

Completed "Interesting Organic Molecules" Table:

Substance	Organic name, function and/or diagram
Oranges	Ascorbic acid (vitamin C); antioxidant, supports immune function, collagen synthesis
Pine trees	Alpha-pinene/beta-pinene; pest defense, pine scent, solvent/aromatic ingredient
Ester #1 (Ethyl acetate)	Ethyl acetate; solvent for paints/adhesives, food flavoring agent
Protein hemoglobin	Function: Transports oxygen from lungs to body tissues, carries carbon dioxide back to lungs
Glucose (sugar)	D-glucose; primary cellular energy source, metabolic fuel for all living organisms

7. Hydrocarbon Uses

Hydrocarbon	Common Practical Use
Propane	Portable fuel for grills and outdoor heating
Benzene	Industrial solvent, precursor for plastics

8. Methane Structural Formula

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

(or condensed structural formula: $\text{CH}_4$, representing a tetrahedral molecule with a central carbon bonded to four hydrogen atoms)
