Chem 1113 Chapter 10

Line Formula: A simplified way to represent organic molecules.
- Simplest Representation: This formula shows only the essential components of the molecule without detailing every atom indicated.
- Carbon at Corners:
  - In a line formula, carbon atoms are presumed to be located at the "corners" of lines or where lines intersect.
  - A carbon atom is also assumed at the end of a line when no additional atoms are explicitly written.
- Hydrogens on Carbons:
  - Each carbon atom is assumed to have enough hydrogen atoms to satisfy its tetravalency (four total bonds).
  - This means each carbon will be bonded to enough hydrogens to make a total of four connections (bonds).

Structural Formula: The detailed representation showing every atom and bond explicitly.
- Visual representation of all carbon (C) and hydrogen (H) atoms including the bonds between them.
Condensed Formula: A more compact representation that summarizes the structure.
- For hexane: C6H14 represents the entire compound without needing to illustrate every bond.
Line Formula: A skeletal representation that emphasizes connectivity and structure without showing all atoms.
- The line formula for hexane would show a continuous line with implied carbons at the ends and intersections, while hydrogens are not explicitly shown.
