Write Lewis dot structure of CO molecule. |
|
Answer» Solution :(i) C [He] `2S^(2) 2p^(2)`, So valence electron = 4 O [He] `2s^(2) 2p^(4)`, So valence electron = 6 `therefore` Total valence electron in CO = 10 (ii) The skeletal structure of CO is written as C - O . (iii) Draw a single hnnci (ONE shared electron pair) between C and O and complete the octet on O, the remaining two electrons are the lone pair on C.  OR `:C underset(larr)(=) O: ` Lewis structure `xx` Electron of C (iv) This does not complete the octet on carbon and hence we have to resort to multiple bonding (in this case a triple bond) between C and O atoms. This satisfies the octet rule condition for both atoms.  C and O has triple bond. Two COVALENT bond one coordinate bond. Note: Triple bond is three. One coordinate bond and two covalent bond between C and O. In co- ordinate bond both electron is DONATED by oxygen. |
