1. What is the electron-domain (charge-cloud) geometry of ICl5.
2. What is the molecular geometry of .
3. Ignoring lone-pair effects, what is the smallest bond angle in ?
4. Which choice best describes the polarity of .
- The molecule is polar and has polar bonds.
- The molecule is nonpolar and has polar bonds.
- The molecule is polar and has non-polar bonds.
- The molecule is nonpolar and has non-polar bonds.
Answer:
- There are 6 electron pairs around the central I atom
=> electron-domain geometry is octahedral
- 5 I-Cl bond pairs and 1 lone pair
=> molecular geometry is square pyramidal
-
Smallest bond angle = 90 degrees
-
The I-Cl bond is polar and the molecule is not fully symmetric
=> The molecule is polar and has polar bonds
