Question

Quizplus · Accepted Answer

Response A: Connectivity is wrong. In a condensed structural formula, atoms in parentheses are attached to the previous atom (unless the parentheses start the formula, in which case they are attached to the following atom).
Response B: Connectivity is correct, but the number of electrons is incorrect. The first two carbons in this drawing have open octets.
Response C: Connectivity and electrons are correct. However, this structure shows charge separation and open octets. It is NOT the best Lewis Structure.
Response D: CORRECT!
