Tham khảo sách 'chemistry part 13, julia burdge,2e (2009)', khoa học tự nhiên, hoá học phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | CHAPTER 8 Chemical Bonding I Basic Concepts Draw the Lewis structure for carbon disulfide CS2 . Strategy Use the procedure described in steps 1 through 6 on page 291 for drawing Lewis structures. Think About It Counting the total number of valence electrons should be relatively simple to do but it is often done hastily and is therefore a potential source of error in this type of problem. Remember that the number of valence electrons for each element is equal to the group number of that element. Setup Step 1 C and S have identical electronegativities. We will draw the skeletal structure with the unique atom C at the center. s-c-s Step 2 The total number of valence electrons is 16 six from each S atom and four from the C atom 2 6 4 16 . Step 3 Subtract four electrons to account for the bonds in the skeletal structure leaving us 12 electrons to distribute. Step 4 Distribute the 12 remaining electrons as three lone pairs on each S atom. S-C-S Step 5 There are no electrons remaining after step 4 so step 5 does not apply. Step 6 To complete carbon s octet use one lone pair from each S atom to make a double bond to the C atom. Solution Practice Problem A Draw the Lewis structure for NF3. Practice Problem B Draw the Lewis structure for CIO7- Checkpoint Drawing Lewis Structures Identify the correct Lewis structure for formic acid HCOOH . a H C O O H b H 6 C b H c H 0 C O H Identify the correct Lewis structure for hydrogen peroxide H2O2 . H Lewis Structures and Formal Charge Multimedia Chemical Bonding formal charge calculations. So far you have learned two different methods of electron bookkeeping. In Chapter 4 you learned about oxidation numbers K4 Section and in Section you learned how to calculate partial charges. There is one additional commonly used method of electron bookkeeping namely formal charge which can be used to determine the most plausible Lewis structures when more than one possibility exists for a compound. Formal charge is .
