Bond energies in Organic Chemistry

Bond energy depends on many factors:

Only One of them is difference in electronegativity (polarity):

the greater the difference, the stronger the bond, due to extra energy required to separate the electrostatic attraction.

C-N (305) < C-C(346) < C-O (358) < C-H (413) < H-H (436) < C-F (489)

C=C ~ C= N (615) < C=O (749)
