Sketch the most likely structure of PC13Br2 and explain your reasoning. For each of the following bonds, indicate which atom is more negative, then rank the series in order of polarity. C-N N- C-I 0-C1 P-Br S-C1 3.41 Give Lewis dot structures and shapes for the following: a. VOC13 b.PC13 c.SOF4 d.S03 e.IC13 f.SF6 g.IF7 h.XeO2F4 i.CF2C12 j.P406 (P406 is a closed structure with the overall tetrahedral arrangement of phosphorus atoms; an oxygen atom bridges each pair of phosphorus atoms.)
