A) I & ii
B) ii & iii
C) ii & iv
D) I & iii
Correct Answer: A
Solution :
(iii) \[Ph-C{{H}_{2}}-O-Ph\xrightarrow{Conc.Hl}Ph-OH+Ph-C{{H}_{2}}-I\] (iv) \[C{{H}_{3}}-\underset{\begin{smallmatrix} \,\,\,\,\,| \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,H-C{{H}_{2}}-O-C{{H}_{2}}-C{{H}_{3}}\xrightarrow{conc.Hl}\]\[+C{{H}_{3}}-\underset{\begin{smallmatrix} \,\,\,\,\,\,\,| \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,H-C{{H}_{2}}\,-l\,+C{{H}_{3}}-C{{H}_{2}}-OH\]
