Which of the following is/are possible Lewis structures for C₂H₆O?

Question

Quizplus · Accepted Answer

It is impossible to draw a Lewis structure for this compound as written because it violates the octet rule (sulfur has 10 valence electrons, while oxygen has 8). However, by rearranging the atoms, we can come up with two possible Lewis structures that satisfy the octet rule for all atoms involved. 
Lewis structure 1: 
S=C=S-O-S-O-H
|
H
Lewis structure 2: 
H-O-S-O-C=S=S-OH
|
H 
Therefore, the correct answer is D, as there are two possible Lewis structures for this compound.
