| \[\underset{IV}{\mathop{C{{H}_{3}}\overset{\oplus }{\mathop{C}}\,{{H}_{2}}}}\,\] |
A) IV < III < II < I
B) IV < II < III < I
C) II < IV< III < I
D) I < II < III < IV
Correct Answer: B
Solution :
Benzyl carbocation is more stable then alkyl \[(C{{H}_{3}}\overset{\oplus }{\mathop{C}}\,{{H}_{2}})\]. \[C{{H}_{3}}O-\] and \[C{{H}_{3}}-\], both stabilize benzyl carbocation and among them\[C{{H}_{3}}O-\] is more stable then \[C{{H}_{3}}-\]. Thus, correct order of stabilities will be IV < II < III < I
