Question
Acetone is a solvent that many will use in organic chemistry lab this year, its molecular formula can be written as CH3COCH3. A possible Lewis Dot Structure (LDS) for it is shown. Remember that the correct LDS is the one that would be most energetically stable. Which of the following statements is most correct for it? O a. This is the correct LDS for acetone. Ob. This LDS is incorrect because it contains too many electrons overall. .This LDS is incorrect because there is an atom with too many electrons around it. d. This LDS is incorrect because there is an atom with an incomplete octet. e.This LDS is incorrect because there is charge separation. Of. This LDS is incorrect because it contains too many electrons overall and there is an atom with too many electrons around it O&. This LDS is incorrect because there is an atom with an incomplete octet and because there is charge separation.Explanation / Answer
The correct answer is option F
There are too many electrons overall and there is an atom ( middle Carbon) with too many electrons aroud it
Middle carbon has 10 electrons around it which makes it over octet ( 4 bonds around carbon gives 8e- and 1 lone pair on C gives 2e- thus total 10 which is against octet rule)
