Which of the following is the correct method for synthesising methyl tert-butyl ether ad why? (i) (CH_(3))_(3)CB r+NaOM eto (ii) CH_(3)Br+NaO-tert-Buto |
Answer» Solution :(ii) Substitution always competes with elimination. Since `3^(@)` alkyl halides PREFERENTIALLY UNDERGO elimination while `1^(@)` alkyl halides preferentially UNDERGOES substitution, THEREFORE, reaction (i) will undergo elimination to give isobutylene while reaction (ii) will undergo substitution to give t-butyl methyl ether.
