Document Summary
Ci homolysis w heat or light t ti. Formed t electron donating more stable at bond association energy easier. C look planar not structure stereoselective reaction are homolysis uses half head. 2 electrons equilibrium reaction resonance retro synthesis reaction showing at previous step. Lower bond stable more association to easy energy form. Bond association energy bengal allylic l 3 l 2 l l a methyl so stability benzyl 7 allylic. Benzyl be can more are delocalized stable on because it other carbons. Ha j on go radical until react w are. E termination can also adding oxygen occur by. 0 d radical butulated e added for stability b. Chlorination results in exothermic lit ratio and is. Nbs is isomers used so that used for allylic propagation there isn"t multiple y p p g. Br m tertiary n to t t n. 134 bond length changed because of orbital g g conjugated l isolated isolated system example.
