Chemistry - GOC Question with Solution | TestHub
In each of the reactions below, determine which compound is the nucleophile and which compound is the electrophile. Which of the following is correctly identified?
(a) 
(b) 
(c) 
(d) 
Options:
Answer:
Solution:
To determine which compound acts as the nucleophile and which acts as the electrophile, identify the electron donor and electron acceptor in the reaction. The nucleophile is the electron-rich species (possessing a lone pair or a π bond) that attacks the electron-deficient species, which is the electrophile.
(a) HO- is the nucleophile; ethylene oxide is the electrophile.
(b) H2O is the nucleophile; the bromonium ion is the electrophile.
(c) H2O is the nucleophile; the tert-butyl cation is the electrophile.
(d) The phenoxide ion is the nucleophile; chloromethane (MeCl) is the electrophile.
Answer: (B)
