Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

in first example see the alpha hydrogen more the alpha hydrogen more the hyperconjugation more will be the stability of carbocation. in second example, if the ring size is less then there would be more%s character and more the s character more will be the electronegative and less the stability of cation hence stability of carbocation decrease as ring size decrease.

explanation--
sir m not getting....this....confused in relation between s character and ring size
bond konsa dekhna hota andr vala ya bahr vala
ring size directly proportional to % s characters. here we will check outer bond angle... simple agr ander ka bond angle bdega to bahr ka km hoga na so % s bhi ring size k sath km hoga or EN of ring km hoga so - will be decrease
sir ye dwkho fr
no shweta, yha bond pair bond pair repulsion increase hoga because internal bond angle increase ho rha he to exo bond angle decrease hoga na
samagh ni aa rha
shweta, yha VSEPR theory use kro.. jb internal bond angle bdega to C-C and C-H bond close ayege. or we know that bp-bp k bich me repulsion hota he so outer bond angle decrease hoga
oh sorry sir got it pta ni pehle kyun ni aa rga tha
