1and if the electronegativity increases as alkyl chain increases.. then + I effect should decrease as the tendency of alkyl groups to donate electrons decrease... but then why + I effect also increase with the increse in alkyl chain?
Why on increasing the alkyl chain + I effect of alkyle groups increases/

62umm.. this is a very tough question for me.. i mean i have always taken it as a fact..
see it is due to the +I effect of each carbon atom..
each carbon has a pushing(+I) effect on elctrons..
This push is effective upto 2-3 carbons..
It is like a chain of people pushing the front one .. so the more no of people the better the push!
Basically Carbons push electrons!
1n why does electronegativity increases on increasing alkyl chain?
62because now there are more no of carbons pushing the electrons!
I mena the 1st carbon will have its own pushing effect(+I)
The 2nd will have a weaker one because of the distance..
so on for each additional carbon..
162there is no electro-negativity of the alkyl group..
carbon-carbon have no difference in electro-negativity!
Electronegativity, is a chemical property that describes the ability of an atom (or, more rarely, a functional group) to attract electrons (or electron density) towards itself in a covalent bond
Here we have no functional group or atom!
1it the alkyl group is attached to any functional gropu then???????
62Then there will be electronegativity of "functional gropu " not the alkyl group
