Partial bond polarization in Nitromethane.

  1. Sep 9, 2011 #1
    1. The problem statement, all variables and given/known data

    Using delta+ and delta-, show the polarization of the bonds in nitromethane.


    2. Relevant equations

    None, he just wrote that on the board. Had to look up the molecule on google. http://en.wikipedia.org/wiki/Nitromethane

    3. The attempt at a solution

    I assume the delta + delta - means the partial charges. Nitrogen has electronegativity value roughly .5 above Carbon. Oxygen has electronegativity value roughly .4 above nitrogen.

    I would assume then that Nitrogen is partial negative, and the bond between oxygen and nitrogen is non-polar covalent. But it seems odd to me that nitrogen would have a negative partial charge when it is bonded to two atoms more electronegative than it, albeit only by .4
