Please note that "geometry" refers to the molecular or ionic geometry. A. The Lewis diagram for SeOF2 is: :0-Se-F: | F: The electron-pair geometry around the Se atom in SeOF2 is There are lone pair(s) around the central atom, so the geometry of SeOF2 is B. The Lewis diagram for CH4 is: HICIH H-C-H The electron-pair geometry around the C atom in CH4 is There are lone pair(s) around the central atom, so the geometry of CH4 is

Draw the lewis and 3D Structure for these. please be neat as possible.

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,…
