A) \[{{\operatorname{F}}_{3}}\overset{+}{\mathop{C}}\,>{{F}_{3}}C\,-\underset{|}{\overset{|+}{\mathop{C}}}\,>\overset{+}{\mathop{C}}\,{{H}_{3}}\]
B) \[{{H}_{3}}\overset{+}{\mathop{C}}\,>{{F}_{3}}C\,-\underset{|}{\overset{|}{\mathop{C}}}\,>\overset{{}}{\mathop{{{F}_{3}}}}\,\overset{+}{\mathop{C}}\,\]
C) \[{{F}_{3}}\overset{+}{\mathop{C}}\,-{{\underset{|}{\overset{|}{\mathop{C}}}\,}^{+}}>\,\,{{F}_{3}}\overset{+}{\mathop{C}}\,>\,\overset{{}}{\mathop{{{H}_{3}}}}\,\overset{+}{\mathop{C}}\,\]
D) \[{{F}_{3}}\overset{{}}{\mathop{C}}\,-{{\underset{|}{\overset{|}{\mathop{C}}}\,}^{+}}>\,\,{{H}_{3}}\overset{+}{\mathop{C}}\,>\,\overset{{}}{\mathop{{{F}_{3}}}}\,\overset{+}{\mathop{C}}\,\]
Correct Answer: B
Solution :
-1 group destablises carbocation and since inductive effect decreases with increasing length of carbon chain. Therefore [b] is the correct option.You need to login to perform this action.
