39 multiple choice 2 points the formal charge on oxygen in dimethyl ether, ch3och3, is______ 0 -1 +2 +1 previous
Answer
Answer:
0
Explanation:
Step1: Recall formal - charge formula
Formal charge = Valence electrons - Non - bonding electrons - $\frac{1}{2}$ Bonding electrons
Step2: Determine oxygen's valence electrons
Oxygen has 6 valence electrons.
Step3: Identify non - bonding and bonding electrons
In $CH_3OCH_3$, oxygen has 4 non - bonding electrons (2 lone pairs) and 4 bonding electrons (2 single bonds).
Step4: Calculate formal charge
Formal charge = 6 - 4 - $\frac{1}{2}\times4$ = 6 - 4 - 2 = 0
