Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
\[R-C{{H}_{3}}\xrightarrow[{}]{Cr{{O}_{2}}C{{l}_{2}}}A\xrightarrow[{}]{{{H}_{2}}O}B\] Which of the statements about the reaction are correct? (1) If R is phenyl group, compound A is of brown colour (2) Compound B is an aldehyde (3) The reaction is called oxo reaction (4) Compound A is an acidA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
\[R-C{{H}_{3}}\xrightarrow[{}]{2Cr{{O}_{2}}C{{l}_{2}}}R-\underset{\begin{smallmatrix} (addition\text{ }product) \\ \,\,\,\,\,\,\,\,\,\,\,\,\,'A' \end{smallmatrix}}{\mathop{C{{H}_{3}}.2Cr{{O}_{2}}C{{l}_{2}}}}\,\] \[\xrightarrow[{}]{{{H}_{2}}O}\underset{'B'}{\mathop{RCHO}}\,\] If R = phenyl. ?A' is of brown colour. The reaction is called Etard's reaction.You need to login to perform this action.
