Quick explanation
Outline nucleophilic substitution mechanisms with OH-, CN- and NH3
- This point belongs to Halogenoalkanes, especially Nucleophilic substitution.
- You need to be able to outline nucleophilic substitution mechanisms with OH-, CN- and NH3.
- The key ideas to know are substitution.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Nucleophilic substitution to exam-style questions, flashcards, and revision notes for Halogenoalkanes.
Quick student answer
Which of the following nucleophiles can participate in a nucleophilic substitution reaction with a halogenoalkane?
Direct answer
OH-
Key terms
- Nucleophile: A species that donates an electron pair to form a chemical bond in a reaction.
- Leaving group: An atom or group that can depart from the parent molecule, allowing for nucleophilic attack.
Common trap
Confusing SN1 and SN2 mechanisms: Remember that SN1 involves a two-step mechanism with a carbocation intermediate, while SN2 is a one-step process with a direct attack by the nucleophile.
