A) Fehling's reagent
B) Grignard reagent
C) Schiff's reagent
D) Tollen's reagent
Correct Answer: B
Solution :
\[\underset{\text{Aldehyde}}{\mathop{R-\underset{\underset{H}{\mathop{|}}\,}{\mathop{C}}\,=O}}\,\,+\underset{\text{Grignard}\,\text{reagent}}{\mathop{R-Mg-X}}\,\to R-\underset{H}{\mathop{\underset{|}{\mathop{\overset{R}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OMgX\] \[\underset{\text{Ketone}}{\mathop{R-\underset{\underset{R}{\mathop{|}}\,}{\mathop{C}}\,=O}}\,\,+R-Mg-X\to R-\underset{R}{\mathop{\underset{|}{\mathop{\overset{R}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-O-MgX\]
