1.	Which of the following is the most stable intermdiate formed during the acid catalysed dehydration of neopentyl alcohol
Answer» `(CH_(3))_(3)Coverset(o+)(C)H_(2)` `CH_(3)overset(o+)(C)HCH_(2)CH_(3)` `(CH_(3))_(2)overset(o+)(C)CH_(2)CH_(3)` all the THREE are equally stable. Solution :The NEOPENTYL alcohol gives more stable `3^(@)` carbocation as an intermediate via rearrangement INVOLVING methyl shift. `(CH_(3))_(3)C CH_(2)OH underset(-H_(2)O)overset(H^(+))rarr (CH_(3))_(3)C CH^(o+) overset("Methyl shift")rarr underset(3^(@)-"carbocation")((CH_(3))_(3)overset(o+)(C)CH_(2)CH_(3))`
