👉👉Wagner-Meerwein rearrangement
mechanism

👉In this Reaction ....

👉when a alcohol containing two or three alkyal or aryl group on the b carbon atom is treated with acid,

👉reshuffling of atom or group take place and give rise to product with different carbon skeleton.

👉This type of rearrangement is called Wagner-Meerwein rearrangement.
Mechanism.

👉The OH group of 3,3dimethyl 2butanol abstract a proton from the acid and formation of oxonium ion.and now h2o is also act as a leaving group.

👉This oxonium ion readily loses a water molecule to produce a secondary carbonium ion.

👉due to loss of water these show formation of a carbonium ion .And driving force for the migration of methyl is provided by the increase stability of the rearranged on which happens to be a tertiary carbonium ion.

👉A proton is lost from the newly formed carbonium ion to form the corresponding olefin.

👉And formation of a product 2,3 dimethyl 2 butene.
