Problem

Given the skeleton structure shown below, what is(are) the correct Lewis electron dot structure(s)? For this question, neglect the formal charges on each atom. 

O O

Solution

O has a bonding preference of 2 with 2 lone pairs on it. If there are only 2 Os, then they must form two bonds between them to satisfy the bonding preference and the octet rule. 

1st structure has triple bond between the O which is not valid and disobeys the octet rule
