When is an Elimination 2 reaction more likely to take place?

[gauss44]

When is an Elimination 2 reaction more likely to take place than any other reaction (more likely than SN1, SN2, E1)? Details and examples welcome.

I'm reviewing this for a student I'm tutoring and seem to have forgotten what makes E2 happen over the other reactions. Thanks!

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
