Answer 1

CH3 CH3 OH 10. H20 option:C H2s04 Mechanism: CH3 CH3 H2 504 Or Ht MOre Stablethanl) because it is 3 carbocation J) CH3 3t is Less Stauble than carbocaton (T) because it is 2 combocation so, Mechanism goes through the canbocafion (I) CH3 OH H20 -H+ + H20 H20 11 Ophion: c H2504 OH 37 Mechanism: Reamramgement H2O40T 2-cam bocafion 3'capahon Here peampamgement oecur because due t0 this mearpamgement a' cambocatio becomes 3 combocai on. which so, Reamnangement Occur dve te the Staole Steubilization of combo to give Cation.
