Step 1:: Draw the Lewis structure for CF^2O.
Start by placing the most electronegative atom, oxygen (O), in the center with the two fluorine (F) atoms and the carbon (C) atom surrounding it. Then, add all the valence electrons for each atom.
Step 2:: Add single bonds.
Connect each pair of atoms with a single bond (one line or dash). This will use up 4 electrons for each bond (2 electrons from each atom).
Step 3:: Distribute remaining electrons.
After adding single bonds, distribute the remaining electrons to complete the octets for all atoms except hydrogen (H). In this case, there are no hydrogen atoms.
Step 4:: Add lone pairs if needed.
If any atoms do not have a complete octet after forming single bonds, add lone pairs of electrons to complete their octets. In this case, no additional lone pairs are needed.
Step 5:: Count bonds and lone pairs.
- Number of single bonds around the central atom (carbon, C): 2 - Number of double bonds around the central atom: 0 - Number of triple bonds around the central atom: 0 - Number of lone pairs around the central atom: 2
Step 6:: Determine electron and molecular geometries.
- Electron geometry: tetrahedral (since there are 4 regions of electron density around the central atom) - Molecular geometry: linear (since there are only 2 regions of electron density around the central atom, ignoring lone pairs)
Step 7:: Calculate bond angle.
The bond angle in a linear molecule is 180 degrees.
Step 8:: Determine polarity.
Since there is a difference in electronegativity between carbon, fluorine, and oxygen, this molecule is polar.
Final Answer
- Number of single bonds around the central atom (carbon, C): 2 - Number of double bonds around the central atom: 0 - Number of triple bonds around the central atom: 0 - Number of lone pairs around the central atom: 2 - Electron geometry: tetrahedral - Molecular geometry: linear - Bond angle: 180 degrees - The molecule is polar.
