A) only i & ii
B) only iii & iv
C) only I & iv
D) i, ii, iii & iv
Correct Answer: D
Solution :
(i) \[{{C}_{6}}\,{{H}_{6}}+C{{H}_{3}}COCl\xrightarrow{Anhy.AlC{{l}_{3}}}Ph-\overset{\begin{smallmatrix} O \\ \,|| \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\] (ii) \[{{(Ph-C{{H}_{2}})}_{2}}\,Cd+2C{{H}_{3}}COCl\]\[\xrightarrow{{}}Ph-C{{H}_{2}}-\overset{\begin{smallmatrix} O \\ \,|| \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\] (iii) \[C{{H}_{2}}-C\equiv CH\,\xrightarrow{HgS{{O}_{4}}}\,C{{H}_{3}}-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\] (iv) \[Ph-C{{H}_{3}}\,\xrightarrow{(1)\,Cr{{O}_{2}}\,C{{l}_{2}}}\,Ph-CH=O\]You need to login to perform this action.
