Wrlle Lewis structure of Nitrite ion. NO_(2)^(-1) |
|
Answer» Solution :(i) Total ELECTRON : N ( Z = 7) : [He] `2s^(2) 2p^(3)` = 5 valence electron O (Z = 8) : [He] `2s^(2) 2p^(4)` = (6) 2 valences electron = 6 `XX` = 12 (Two oxygen) (ii) Structural PRESENTATION : Electronegativity of N is less than O So N is central atom so the arrangement will be.  (iii) To get octet on N and O double bond is required between N and O.  In this WAY N has one double bond and one single bond. One .O. has one double bond and second .O. has single bond. |
