Interpretation:
The wedge-dashed wedge-line formulas of both A and B are to be drawn and the change in configuration is to be determined.
Concept introduction:
Reaction sequences involve conversion of one
These sequences involve a number of steps carried out by different reagents. Sometimes different reagents give the same products.
Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.
Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.
Nucleophilic substitution reaction is a reaction in which an electron-rich nucleophile attacks the positive or partial positive charge of an atom or a group of atoms to replace a leaving group.
An
An
The involvement of nearby nucleophile substituent to the reaction center in the substitution process is known as neighboring group participation.
Such participation results in an increase of
In this participation, two
