Because silicons lone pair also participates in resonance. Hence 4 pi electrons
why ccl3(-) more stable than cf3(-)?
Due to Vacant d orbital of cl
So resonance takes place in ccl3 but not in cf3 right?
Yes ..@azimuddin_sheikh ..in CCl3- resonance is there not in CF3-
bro in this why 1st is more stable?
See this👇 @Azimuddin_Sheikh
@Viraj Bro in which conditions that fact is valid?
here cl lp can't be delocalised ?
It should be delocalised
.. I guess When you are comparing stability between halogen substituted and other group substituted compounds..
I have written in last bracket that for halogens u gotta see inductive first as thats a more dominant factor for them due to their high e-negativity..
Here -I> +R right @Viraj @Azimuddin_Sheikh
Yup. -I dominates +M
Due to EN ?
Hmm yes .. @pratyaksh_tyagi, read that paragraph once itll be clear i gue ss
Bro this fact is not valid in case of comparing both halogens substituted right? @Viraj bro
I feel even then you should see I first..
Dont see it as an exception, just that for halogens inductive effect is to be seen with more effect than other elemnts..
So we compare I effect for halogens first
Ok bro I will
