方智歷屆有機試題 - 考試

bond dissociation energy of homogeneous cleave (Kcal/mol)
C6H5-H (SP2 orbital &conjugation????) 110
CH2=CH-H (SP2 orbital) 108
CH3-H (SP3 orbital) 104
CH3CH2-H (primary) 98
(CH3)2CH-H (second) 95
(CH3)3C-H (tertiary) 92
CH2=CHCH2-H (conjugation) 88
C6H5CH2-H (conjugation) 85

.
我想請問一下在方智歷屆試題中有一題,他是排列radical 的 stable,假如說是CH3C=O radical(中山材料的90碩班有機考試)它的穩定性會介在
哪兩者之間??

拜託各位高手了!!
