WebNucleophile should attach to the tertiary carbon. This is Sn1 reaction. So nucleophile should be substituted with a leaving group . In the given compound, we are given with hydroxide which is not a good leaving group. In order to continue the reaction, we must convert the hydroxide which is a bad leaving group into the good leaving group. WebThe reactivity order of alkyl halides in the case of S N 1 reaction is- 3 0 > 2 0 > 1 0 > methyl. The same reason is responsible for more reactivity of compounds such as benzylic halide and allylic halides towards S N 1 reaction because it leads to the formation of highly stable resonance structures of carbocation intermediates. WebErnest Zinck. 7 years ago. SN1 and E1 — the leaving group leaves first. SN2 and E2 — the leaving group leaves last. SN1 and SN2 — the X:⁻ attacks a carbon atom. E1 and E2 — the X:⁻ attacks a β hydrogen atom. ( 11 votes) did budweiser sell out to a foreign company
