this question is asking to draw the Louis structure of C C. 04 We're gonna start off by counting the total number of valence electrons we need. So carbon has surveillance like Drano four, and chlorine has violence like she owns a seven. And there's four. Chlorine Sze soul. Total number of Ellen's electrons that are available for pairing are 32. To determine the number of bonds we need to determine the tool number of electrons to satisfy the octet rule. Uh, carbon and chlorine need a electrons to satisfy his octet rule, so we'll have a total of five Adams that need eight electrons equaling 40 electrons to satisfy the octet rules. If we subtract the tool number of electrons by the valence electrons available, we have eight electrons that are going to be shared. If we divide that by two, then we have a total of four bonds needed in our Louis structure. Since chlorine only has 17 males electrons, that means that only needs one more electron to be paired with. They're usually on the exterior of the Lewis structures. Carbon will be in the center. We'll draw the Louis are the villains, electrons to be four, and then chlorine will be on the outsides. But trust seven millions. Electrons 34567 in their final, Corinne, 1234567 So for every shared electrons is gonna equal a single bond. So we'll go ahead and make our bonds between the shared electrons between carbon and chlorine, and we'll double check our work. We have 246 Hey, shared electrons or four bonds and then 10 12 14 16 18. Money for me to 24 26 28 30 30 to Valence Electrons total in our Louis structure. So our final structure is, and then with our lone pairs, which I'm gonna mark them as dashes for our pairs. But you can go ahead and draw the actual dots 2% that Louis fears this will be the final structure for our carbon tetrachloride.
