Question 23
Which compound is formed from bromoethane in a nucleophilic substitution reaction? A CH₃CN B CH₃CH₂NH₂ C CH₂=CH₂ D CH₃CH₂OSO₄OH
Worked Solution & Example Answer:Which compound is formed from bromoethane in a nucleophilic substitution reaction? A CH₃CN B CH₃CH₂NH₂ C CH₂=CH₂ D CH₃CH₂OSO₄OH - AQA - A-Level Chemistry - Question 23 - 2022 - Paper 3
Step 1
B CH₃CH₂NH₂
Answer
In a nucleophilic substitution reaction, bromoethane (C₂H₅Br) reacts with ammonia (NH₃) to create an amine. The compound formed is ethylamine, represented by the formula CH₃CH₂NH₂. This process involves the substitution of the bromine atom with the amine group, which acts as a nucleophile in the reaction.
