To identify the appropriate headings to complete the given table, we should consider the nature of the information presented in both the top and bottom rows of the table.
### Analysis
1. Top Row:
- The entries in the top row are chemical notations. Specifically, they are:
- [tex]$R - OH$[/tex]
- [tex]$R-O-R^{\prime}$[/tex]
- [R]C([R])=O
- [R]C=O
- [R]C(=O)O
- [R]OC([3H])=O
- These notations specify different organic compounds or classes of compounds defined by their functional groups. A functional group in organic chemistry is a specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
2. Bottom Row:
- The entries in the bottom row describe the uses of the above-mentioned compounds:
- Beverages, Fuel
- Anesthetic, Organic solvent
- Organic solvent
- Preservative, Adhesive
- Weak acid, Vinegar, Fats
- Fragrances
- These terms clearly indicate practical applications or uses of the compounds in various fields.
### Conclusion
Given the nature of the information:
- The top row details the functional groups of the compounds.
- The bottom row lists their uses.
Therefore, the appropriate headings for this table should be:
Top row heading: Functional group
Bottom row heading: Uses
Thus, the correct headings for the table are:
- Functional group (Top row)
- Uses (Bottom row)
