Document Summary
Ah undergo elimnation reactions with bronsted lowry bases. One of the most common methods to introduce a pie bond and prepare an alkene. An example of a b elimnation, because it involves loss of elements from two adjacent atoms. The a carbon bonded to the leaving groiup x, and the b carbon adjacent to it. Base removes a proton on the b carbon, thus forming h-b+ 2. the electron pair in the b c-h bond forms the new pie bond between the a and b. carbons. The electron pair in the c-x bond ends up on halogen, forming the leaving group: x. Most common bases used in elimn ation reactions are negatively charged oxygen compounds such as 0oh and its alkyl derivatives. Find the a carbon-the sp3 hybridized carbon bonded to the leaving group. Remove the elements of h and x from the a and b carbons and form a pie bond.
