I can't draw on the wiki but here are the names: heptanes, 2 methyl hexane, 3 methyl hexane, 2,3 di methyl pentane, 3,3 dimethyl pentane, 2,2 dimethyl pentane, 3 ethyl pentane, and 2,2,3 trimethyl butane. 22. Polar bonds can be equalized by shape of the overall molecule so it is nonpolar. Ex. Carbon tetracholide 23. Repel 24. More than one Lewis structure for he same molecule. 25. PH3 - p in center with 3 H's and one lone pair, trigonal pyramidal, polar. B. s in middle with a lone pair, one oxygen has a double bond with the s and two lone pairs. The other oxygen has a single bond to the s with 3 lone pairs, bent, polar, c. c in middle with a single bond to H and 3 single bonds to the 3 Br's. each Br has 3 lone pairs, tetrahedral, and polar. D. P in middle with oxygens coming off with a single bond to each oxygen each oxygen has 3 lone pairs. Tetrahedral, non polar. E. c triple bonded to the other c with a single bond to a H from each carbon. Linear, and nonpolar. Chapter 9-10 1D 2B 3B 4D 5C 6A 7 q = 10,125 J 8.
