A) \[{{(C{{H}_{3}})}_{3}}C\overset{+}{\mathop{C}}\,{{H}_{2}}\]
B) \[{{(C{{H}_{3}})}_{3}}\overset{+}{\mathop{C}}\,\]
C) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}\]
D) \[C{{H}_{3}}\overset{+}{\mathop{C}}\,HC{{H}_{2}}C{{H}_{3}}\]
Correct Answer: B
Solution :
The order of stability of carbocation is \[{{\text{3}}^{o}}>{{2}^{o}}>{{1}^{o}}\] (a) \[\underset{({{1}^{o}})carbocation}{\mathop{{{(C{{H}_{3}})}_{3}}C-\overset{+}{\mathop{C}}\,{{H}_{2}}}}\,\] (b)\[\underset{({{3}^{o}})carbocation}{\mathop{{{(C{{H}_{3}})}_{3}}{{C}^{+}}}}\,\] (c) \[\underset{({{1}^{o}})carbocation}{\mathop{C{{H}_{3}}C{{H}_{2}}\overset{+}{\mathop{C}}\,{{H}_{2}}}}\,\] (d) \[\underset{({{3}^{o}})carbocation}{\mathop{C{{H}_{3}}\overset{+}{\mathop{C}}\,HC{{H}_{2}}C{{H}_{3}}}}\,\] \[{{\text{3}}^{\text{o}}}\]carbocation i.e., \[{{\text{(C}{{\text{H}}_{3}}\text{)}}_{3}}{{C}^{+}}\]is the most stable carbocation.You need to login to perform this action.
