Document Summary
Chapter 9: elimination reactions of alkyl halides competition between. 9. 1 the e2 reaction: h is removed from a primary carbon (bonds to oh ion to form h2o). Br is: alpha carbon (a symbol) carbon to which the halogen is attached, beta carbon (b symbol) carbon adjacent to alpha carbon, b-elimination reaction (or 1,2-elimination reaction) when proton is. Double bond is formed from leftover electrons from removal of h. removed from beta carbon first. on the inside (not the outside) hydrogen is removed from the b-carbon that is bonded to the fewest hydrogens. The more substituted alkene will be the one formed by removing a proton from the b-carbon bonded to two hydrogens: relative reactivities of alkyl halides in an e2 reaction. In transition state leading to alkene c-h and c-br bonds are partially broken simultaneously more stable intermediate is one with double bond.
