As of this date, Scribd will manage your SlideShare account and any content you may have on SlideShare, and Scribd's General Terms of Use and Privacy Policy will apply. Learn more.

The difference between SN1 and SNi is actually that the ion pair is not completely dissociated, and therefore no real carbocation is formed, which else would lead to a racemisation.

How does anthranilic acid and pyrogallol used in inorganic chemistry? This back-side attack causes an inversion (study the previous slide): after the leaving group leaves, the other substituents shift to make room for the newly-bonded nucleophile, changing the stereochemistry of the molecule. Discuss the structure and bonding  of Zeise’s  salt? The term SNi stands for substitution nucleophilic internal. give significance of resonance and resonance energy. charge transfer( CT ) or electron donor acceptor( EDA) complexes and their properties. The reaction is Sn2, and even though 1-chloro-2,2-dimethylpropane is a primary chloride, it is more sterically hindered than 2-chloropropane, which is secondary. Some examples for this reaction were reported by Edward S. Lewis and Charles E. Boozer in 1952.
