Why E2 is favored over SN2
Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so? Are there any general enthalpy data or something that explains this? I have searched the interenet for a while without finding any mathematical explanation as for example a general difference in enthalpy. And I wanted a that kind of explanation or some other justification. Can anyone help out with that? Some numbers like enthalpy would be great or a explanation in general.
