The molecule that contains the electrophile and the leaving functional group is called the substrate. The most general form of the reaction may be given as the following: the path to wealth book

WebNucleophilic Substitution (S N 1 S N 2) Nucleophilic substitution is the reaction of an electron pair donor (the nucleophile, Nu) with an electron pair acceptor (the electrophile). An sp 3 -hybridized electrophile must have a leaving group (X) in order for the reaction to take place. Mechanism of Nucleophilic Substitution WebIn a substitution reaction, one atom (or a functional group) replaces another one. The replacing group is called a “ nucleophile ” and the group being kicked out is called a “ leaving group ”: These reactions occur because of the imbalance of the electron density between the carbon and halogen (leaving group) since it is a polar covalent bond.
