Man !!! It's Organic again !!

a=vinyl
b=Allyl
c=Methyl

c>a>b

Bond Hydrocarbon radical Bond Dissociation Energy (kcal/mole)
CH3-H Methyl 103

CH2=CH-H vinyl 112

CH2=CHCH2-H Allyl 88

http://en.wikipedia.org/wiki/Carbon-hydrogen_bond

a>c>b

Typing error in post2 .

bond dissociation energy of methyl is always greater than the allyl group..

and obviously c has highest ..

so b<c<a is true

Can someone please give the reason why this is so that B-E of methyl > allyl > vinyl ??????

aveek.. u try reasoning out dude... the ease of removal of hydrogen...

then u can get the asnwer yourself :)
