Question

8.107 Problems 8.97. In which of the following molecules does the sulfur atom have an expanded valence shell? (a) SF; (b) SFS (C) SF; (d) SF2 gulec does the phosphorus

please explain

Answer 1

97 (0) SF Draw its octet diagram: 80 s has 6 Valence electron and it Share each with 6 F alomy as Shown, so total electron on 's become 6x2 = 12 , which is more then 8 octed Rule says that outer shell must have 8 electrons. SO, SF has expanded octet. I 16 SFS It should be sest or SFS SFS+ SFG uz loen 0 U 12e- In both Cases, s' has more than 8e- Hence, it has expanded octet.

10e- I (0) Sty: 100 . valente adoms, so is shared with & electrons, 4 total electron in its octer Yx2 + 2 = 10 Sfy has abo expanded oltet. 10) SF₂: xSx.) 8e- o ctet in Complete
expanded valence shell means the species having more than 8 electrons in their outermost shell or more than 8 electrons in its octet

So answer is ABC
