I. \[\phi -\overset{\oplus }{\mathop{\underset{\begin{smallmatrix} | \\ \phi \end{smallmatrix}}{\mathop{C}}\,}}\,-\phi \] |
II. \[\phi -\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\] |
III. \[C{{H}_{2}}=CH-\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\] |
IV. |
A) I > IV > II > III
B) I > II > III > IV
C) I > II > IV > III
D) I > III > IV > II
Correct Answer: A
Solution :
