Problem Lewis Symbols and Structures Write Lewis structures for the following: (a) H2 (b) HBr (PCs (d) SF2 (e) H2CCH2 (f) HNNH (g) H2CNH (h) NO ()N2 ) Co (k) CN

Please help me solve part J as the answer in the book makes no sense, thank you

Answer 1

Lewis Symbols and Structure: write Lewis structure for the (1) co co : do: C . be se Valence electron of carbon is 4 and oxy- gen is 6 There is two bonds between to the carbon and oxygen by Shearing of two electron of carbon and two electron of oxygeni - after forming bond In this case carbon has 6 electrons and oxygen has 8 electrons it means octate has not completed. so this structure is not stable and this Structure is not right -os electron Also, we seen that oxygen has two lone pair, one lone pair of oxygen will shean between the carbon and oxygen, so oxygen I will donate one lone pair to carbon.

Now, this structure obey the Octate rule, so this is the stable structure. . Another structure can be drawn be by elema enating the coordination bond between oxy- gen to carbon, the structure will like this - - (-) . (4) CEO se se oxygen is donating the electron pair their fore its charge is ppositive and carbon is acceptin ng the electron pair therefore its charge is negative. But the overall charge of the molecule is zero. This charge is called formal charge. Formal charge means there is no vacancy or their is no extra electron It also obey the octate rule and hence this is the stable structure of co. (Page-2) Scanned with CamScanner
