Question

whats STABILITY OF CARBOCATION INTERMEDIATES and how it works in sn1?

compare the STABILITY OF CARBOCATION INTERMEDIATES what makes a carbon more stable ?

why raking the way ?

Answer 1

The answer is in images
soló- stebility of carbocalios stability := A positively charged species such as a carbocation y La very poor election species. Those groups which can donates electron density to I Cabocation can stabilize it. | And Electron with drawing group can destabilize the caubon catim. donating come weak electron groups like Alky groups, methye, ethye ete, so they can donate the dectron and Cano stabilize the nearby carbocetim. e stability of carbocatims are as follows Tertiarysis secondenyes primary cez mettye How it works in SNI" In SNI reaction, the first step is formation of Cembocation Intermediate. And this is the Rate determining step Became it is slow.

z And the Rate depends upon the activation Energy in which the bond between the carbon and the leaving group I breaks and carbocatio * Mese stable the carbecatim Intermediate, the Bond Breaking step will be fasth. atz Cambocation Intermediate) SNI Mechanism depends upon the righ degree of stability of cabocation intermediate And stept is very fast when a group will add to it. 3

o second step of SNI Reaction! The group adds in etep second at clubocation, so to add to the carbocation, or strike to carbocation the adding group Needs way to strike on it. so, due to this effect some time adding group feels steric linderance in SN, & Sale Reactions, a
