For the purpose of determining formal chages, what is the total number of electrons assigned to the oxygen atom in the Lewis structure of formaldehyde (CH2O)?
a. 8
b. 6
c. 4
d. 2
e. 10
Total no. Of valance electron in O =6
It doesn't depend on the molecule of which O you have taken it will remain constant. Then you will calculate charge.
So. Correct option is b.
