**Isoflurane Structure and Molecular Geometry**

Isoflurane is used as an inhaled anesthetic. The image shows the Lewis dot structure of isoflurane.

**Structure:**

F-C-C-Cl  
|       |  
H  F  O  
|       |  
H-C-C-F  
   
Each carbon (C) is bonded to other atoms, forming an integral part of the molecule's structure.

**Questions:**

1. **What is the bond angle around each carbon center?**

   - Options:
     - 120°
     - 109.5° (Correct answer for tetrahedral geometry, common in sp³ hybridization)
     - 180°
     - 90°

2. **What is the molecular geometry at each carbon center?**

   - Options:
     - Linear
     - Trigonal planar
     - Tetrahedral (Correct due to four single bonds around carbon)

3. **What is the bond angle around the oxygen center?**

   - Options:
     - 120°
     - 109.5° (Correct angle in water and similar structures due to lone pairs)
     - 180°
     - 90°

4. **What is the molecular geometry at the oxygen center?**

   - Options:
     - Linear
     - Trigonal planar
     - Bent (Correct, due to lone pairs pushing bonds on oxygen)
