A) 2, 4- dinitrophenylhydrazine
B) aqueous solution of NaHSO
C) benedict reagent
D) \[{{I}_{2}}\]and \[N{{a}_{2}}C{{O}_{3}}\]
Correct Answer: D
Solution :
\[{{I}_{2}}\] and \[N{{a}_{2}}C{{O}_{3}}\]react with acetophenone \[({{C}_{6}}{{H}_{5}}COC{{H}_{3}})\]to give yellow ppt. of \[CH{{I}_{3}}\] but benzophenone \[({{C}_{6}}{{H}_{5}}CO{{C}_{6}}{{H}_{5}})\]does not and hence can be used to distinguish between them.
