Question

Which molecule has the lowest boiling point?

**Use these molecules to answer questions 14-17.**

**Molecule A:**

- Structure: Tetrahedral
- Central atom: Silicon (Si)
- Surrounding atoms: Four Fluorine (F) atoms, each with three pairs of lone electrons
- Notation: 
  - F atoms are single-bonded to the Si atom.
  
**Molecule B:**

- Structure: Linear
- Atoms: Two Carbon (C) atoms and one Oxygen (O) atom
- Hydrogen (H) atoms: Attached to each C atom (total of six H atoms)
- Lone pairs: Oxygen has two lone pairs of electrons

**Molecule C:**

- Structure: Linear
- Atoms: Three Carbon (C) atoms with alternating single and double bonds to two Oxygen (O) atoms
- Hydrogen (H) atoms: Attached to the terminal C atoms, total of six H atoms
- Oxygen atoms:
  - First Oxygen has two lone pairs and is double-bonded to a C atom
  - Second Oxygen has two lone pairs and is double-bonded to a C atom on the other side

These diagrams illustrate molecular structures that can be analyzed for chemical bonding, geometry, and electron configuration.
