Question

Could you explain why they are correct or wrong?

Lewis Dot Diagrams -- Diatomic Molecules Use the check-boxes to select all (and only) those electron dot pictures for the indicated molecules or ions which are acceptable Lewis structures. [:N:: 0 :] Lewis structure of Not? O :C O : Lewis structure of co? 0:0:0: Lewis structure of Oz? O F:: Lewis structure of Fz? O:N:N: Lewis structure of Nz?

Answer 1

Some Important Step1 we need to find to eg. CN- ( + 4 valere So for CN- - od 4+ 5+1=10 vale Important steps to draw lewis Structure We need to find total number of valence electrons. valene electrons are the outershell electrons) V C+ 4 valence election N45 valence electrons and due to the sign 1 extra valence electron od +5 + 1 = 10 valence electron. Stepa & keep the less electronegative atom at the center, eg. Nless electronegative than o şoxygen No₂ =) ONO Step Then but the two electrons between ator Chautical bond. Step 4 Complete oclets of the atoms Youn a # Lewis structure of Not { Nitrosonium lon} Not Total valence electron = 5+6-1 = 10 10 S-I because of -1 I postive charge SN: 0:7 in the question So the ginen structure is correct Acceptable, # Lewis structure of co { Carbon Monoxide Total valence election = 4+6 =10 (74 076 :06:0. So the given stundure in the question is carrot Acceptable] e as follows ockt aule. leurs structure of a Total Valence electron - 6x2 = 12 0:0. So the ginen structure : 0 : 0 is not correct as it does not satisfy Octet

Leurs structure of Fa Total Valence electron = 7x2 = 14 [Acceptable So the given structure in the question is correct. as follows or satusties octet Lewis structure of Ng Total valence electron - 5x2 = 10. :N::N: So the given structure No is wrong because it does not satisfy octet or does not follow ocket rule
