O ELECTRONIC STRUCTURE AND CHEMICA... Deciding whether a Lewis... Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure [O=C-H]* :0: : CIC CI: [¤¤-6: 0/5 Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: 0 No, it has the right number of valence electrons but doesn't satisfy the octet rule. 000 The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: 0 Alia V No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* X Ar If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example,…
