Why do the C-C bonds rather than the C-H bonds break during the pyroly

1.	Why do the C-C bonds rather than the C-H bonds break during the pyrolysis of alkanes?
Answer» Yes this is right.<br>C-H.It is because the bond length between Carbon and Hydrogen is smaller (Hydrogen radii is smaller that\'s why) than between Carbon and Carbon, so more energy is needed for atomization as the effective nuclear charge on the bonded pair of electrons will be greater
