Use the Table of Electronegativities provided to answer the following question. Choose the more polar bond and identify the element that will act as the negative pole: C-N or C-F
C-N; N is the negative pole |
||
C-N; C is the negative pole |
||
C-F; C is the negative pole |
||
C-F; F is the negative pole |
Ans (d) C-F is more polar and F is the negative pole
As we know E, symbol χ, is a concept that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself.
F is the most electronegative element and higher the electronegative difference , higher is the polarity.
C-F has electronegative difference so it the more polar and those elements having high Electronegativity carry partial negative charge.
F is the negative pole.
