Purpose : The S N 2 reaction is an important bond forming reaction for organic and biological pathways. In this type of reaction one of the partners is the nucleophile and the other is the electrophile. In this lab the nucleophile is the naphthoxide ion while the electrophile is iodobutane, where the idodide ion is the leaving group. In theory the naphthoxide ion will displace the iodide from the iodobutane to form butyl naphthol ether. Structures of Compounds Used: Equation: + Mechanism:
