Yes, thank you. Fixed
]]>Let me have another crack at it. Homolytic cleavage usually happens when you’re breaking a bond between two identical atoms which have a weak bond, such as Br-Br or RO-OR. They have equal electronegativity and therefore the bond isn’t polarized toward one of the atoms. The result is that the bond breaks such that the electrons are distributed symmetrically.

]]>The role of heat in these cases is to fragment a weak bond such as O-O or Br-Br .
Heat, by itself, may excite an electron from HOMO to LUMO in a diene, but this method can lead to a lot more side reactions than if one were just to use light.
Probably a different reaction then.
