What is the difference between UNIMOLECULAR ELIMINATION & BIMOLECULAR ELIMINATION?
Answer:
Unimolecular elimination is the same as a E1 elimination. It is characterized as proceeding through a carbocation transition state. Bimolecular elimination is the same as a E2 elimination. It is characterized as being a concerted process and proceeds through an antipariplanar transition state. Check E1 and E2 reaction mechanisms in your textbook and you will ubderstand what I am trying to explain. Hope this helps.
Reaction Conditions: Strongly basic so the relatively high energy e-'s on the nucleophile/base are likely to be involved in the transition state of the slow step. Thus the conditions favor bimolecular reactions, SN2 or E2.
both are types of elimination reactions, which we study in organic chemistry...
in unimolecular elimination rxn(reaction), in the rate determining step, only one species (ie single molecule) is involved in the rxn...
this is E1 rxn
in bimolecular elimination rxn, in da rate determining step, 2 species(ie 2 molecules) are involved in da rxn..
this is E2 rxn.
hope this helps u...
u can find this information on any good chem books for 11/12 std, cbse or iitjee prep books.
