IIT JEE , AIEEE Forum - Chemistry , Organic Chemistry - organic chemistry [admin]: why alkyl groups behave as electron donors ?

ritu_007

can you explain why alkyl groups behave as electron donors when attached to a

system?

I've repeated my question because unfortunetly my question wasn't answered.so plzz.help me and answer this question as soon as possible.

FOR +I EFFECT ALKYL GROUPS BEHAVES LIKE CARBO CATIONS.SO IT BEHAVES AS ELECTRON DONORS.

ans:
double bonded carbon atom is using sp2 hybrised state so %s character increases therefore double bonded carbon atom is more electronegative than sp3 hybridised carbon thats why alkyl is showing +Ito double bonded corbon sys

Hi,
Your question has been answered.
Please see:

I would recommend you to read all types of electron displacements in organic compounds: Inductive Effect, Resonance and Hyperconjugation.

any group which attrect electron less strongly than hydrogen have +I effect.due to very less electronegativity of sp3 carbon atom these have +Ieffect.

smartgoels

one factor responsible is hyperconjugation

thankyou .the solutions were of great help.
