Allilici
WebAn allylic rearrangement or allylic shift is an organic reaction in which the double bond in an allyl chemical compound shifts to the next carbon atom. It is encountered in nucleophilic substitution . In reaction conditions that favor a S N 1 reaction mechanism, the intermediate is a carbocation for which several resonance structures are possible. Carbocations are ionic species which carry a positive charge on the carbon atom of the molecule. They usually form as an intermediate during various chemical reactions. The stability of carbocations determines by steric hindrance and +I effect of alkyl groups attached to C+of the carbocation. As the +I effect … See more The Modern Periodic table in which all known elements are arranged in increasing order of atomic number.
