Question

w the mechanism of the following reaction, using the curved-arrow notation to indicate the ganization of electron density. Denote all intermediates, lone pairs, nonzero formal charge mtercharges, and reversibility or irreversibility HỌC CH | HCCH excess EtOH H₃C OEt Eto .. H

the mechanism, using a curved arrow, include all the lone pairs, non zero formal charges, countercharges, and reversibility or irreversibility.

Answer 1

- H2C H3C ....CH₃ H3 H H,CÔ CHỊ Et-ÖH HBC, *H,CÔ CH, G H H N Ồ CH3 ot + Et-o Oct * :I? : 1. Нас Et-OH The substrate is the tert alkyl iodide, hence it undergoes C-l bond cleavage first to give tert. carbocation. This carbocation is further stabilized by solvation with EtOH. Then the ethanol act as a nucleophile to form new C-O bond. Leading to ether formation. This mechanism is called as SN1 mechanism.
