How many lone pairs are there in the Lewis structure of O₂? A)3 B)1 C)0 D)4

Question

Quizplus · Accepted Answer

The Lewis structure of OSF2 (Osmium difluoride) shows that osmium (Os) is the central atom with two fluorine (F) atoms bonded to it. Osmium has 6 valence electrons, and each fluorine atom has 7 valence electrons, making a total of 20 valence electrons. In the structure, there are 4 bonds (each F-Os bond counts as 2 electrons), using up 8 electrons. This leaves 12 electrons, which are distributed as lone pairs: 6 on each fluorine atom (3 lone pairs on each) and none on osmium. Therefore, there are a total of 6 lone pairs on the fluorine atoms, and none on osmium, making the total number of lone pairs in the molecule incorrect as per the options provided. It seems there was a misunderstanding in the question's formulation regarding the molecule's composition or the interpretation of lone pairs.
