Please show the mechanistic steps for the following 2
reactions. Thank you for the help.
CH.CH OH products Explanation: Reaction of tertiary alkyl halide with weak nucleophile.CH,CH,OH involves SN substitution reaction and produces racemic mixture of products, H20 - products Explanation: Reaction of tertiary alkyl halide with weak nucleophile,H,O involves SN, substitution reaction and produces racemic mixture of products.
Mechanism Practice Complete the elementary steps below by adding mechanistic arrows to show how the product is formed. For some of the reactions, you will need to determine the products as well. Make sure you show all formal charges and all lone pairs that are involved in the mechanism! Nucleophilic Addition H. +HOCH Proton Transfer (intramolecular) Deprotonation (intermolecular OH +
