Step 1:I'm here to help! Based on your request, I understand that you would like me to create a step-by-step solution for drawing a Lewis structure of the CS^2 molecule.
Here's how to do it:
Step 2:**Find the total number of valence electrons**
- CS^2 contains two carbon atoms (4 valence electrons each) and two sulfur atoms (6 valence electrons each). - Total valence electrons = (2 × 4) + (2 × 6) = 16 valence electrons
Step 3:**Determine the central atom**
- In CS^2, carbon is less electronegative than sulfur, so carbon will be the central atom with each sulfur atom bonded to it.
Step 4:**Draw a skeletal structure**
- Place the central atom (carbon) in the middle, and attach the other atoms (sulfur) to it with single bonds. - C-S-C
Step 5:**Add remaining valence electrons as lone pairs**
- Distribute the remaining electrons to complete the octets for all atoms. - Add one lone pair to each sulfur atom: - :C:S::S:C:
Step 6:**Check for formal charges**
- Calculate formal charges for each atom by subtracting the number of lone pair electrons and one-half of the bonding electrons from the number of valence electrons. - Formal charge on carbon = 4 - (2 × 2) - (2 × 1) = 0 - Formal charge on sulfur = 6 - (4 × 1) - (2 × 1) = 0 - The formal charges are zero, which is ideal.
Step 7:**Final Lewis structure**
- The final Lewis structure for CS^2 is: - :C:S::S:C: **
Final Answer
The Lewis structure for CS^2 is: :C:S::S:C:
