E2 > E1cb > E1 >SN2 >SN1
elimination reaction have higher entropy than substitution becoz elimination occurs at higher temperature ( entropy increases when temperature increase) and second order kinetics have greater entropy than first order kinetics becoz more number of molecules are involved ....
Anurag Ghosh More no. of molecules are involved or formed as products???
Anurag Ghosh Aur E1cb ka E1 se zyada kyun hai entropy?
Anurag Ghosh Arey haan...i didn't noticed...i asked how many of these will show +ve entropy change......Ab wat range u r taking for d entropy of these reactions???(Question becomes a bit confusing..:P).....This is an integer type question....
Swarna Kamal Dhyawala well i guess it must be 3 (the elimination ones)
Anurag Ghosh Why not the Substitution ones???.....
Swarna Kamal Dhyawala becoz in elimination no. of products formed is more ........ and is carried out in high temperature also.......
