Alkyl halides reactions.
Explanation:
- Alkyl halides goes nucleophilic displacement and elimination reactions.
- Tertiary alkyl halides are reactive in Sₙ¹ reactions.
- Whereas primary and secondary halides are reactive in Sₙ² reactions. Sₙ₂ occurs by a concerted mechanism with inversion of configuration.
- Concerted mechanism means occurrence of bond breaking and bond formation at the same time.
- Sₙ² is a bimolecular reaction.
- Whereas the Sₙ¹ reactions are includes reactions in which C-X bond breaks first then nucleophile approaches.
- It is an unimolecular reaction also known as dissociative mechanism.
