Which of the following carbocation is most stable ? (a) (CH_(3))_(3)C

1.	Which of the following carbocation is most stable ? (a) (CH_(3))_(3)C overset(+)(C)H_(2) (b) (CH_(3))_(3)overset(+)(C)(c) CH_(3)CH_(2)overset(+)(C)H_(2)(d) CH_(3)overset(+)(C)HCH_(2)CH_(3)
Answer» Solution :The order of STABILITY of carbocation is : `3^(@) gt 2^(@)gt 1^(@)` (a) `UNDERSET(1^(@) " Carbocation")((CH_(3))_(3)C - overset(+)(C)H_(2))` (b) `underset(3^(@) "Carbocation")((CH_(3))_(3)overset(+)(C))` (c) `underset(1^(@) "Carbocation")(CH_(3)CH_(2)overset(+)(C)H_(2))`(d) `underset(2^(@) "Carbocation")(CH_(3)overset(+)(C)HCH_(2)CH_(3))` Since `3^(@)` carbocations are the most stable, therefore, option (b) is CORRECT.
