Question

The correct Lewis structure for  
shows that the molecule contains two double bonds.

Quizplus · Accepted Answer

The presence of two double bonds in a molecule can be deduced from its Lewis structure by counting the number of valence electrons and arranging them in a way that satisfies the octet rule for all atoms. If there are no lone pairs of electrons on the central atom and all other atoms have a complete octet, then the molecule contains no double bonds. However, if there are one or more lone pairs on the central atom or incomplete octets on other atoms, then double bonds may be present. Without the specific Lewis structure for 11ea8a6b_bbb3_ae37_9ee3_2b703a1ec980_TB6109_11, it is not possible to determine whether it has double bonds or not.
