The most suitable reagent for the conversion of 

R-CH2 -OH →R- CHO is

  • KMnO4

  • K2Cr2O7

  • CrO3

  • PCC (pyridinium chlorochromate)

Solution

D.

PCC (pyridinium chlorochromate)

straight R space minus space CH subscript 2 OH space rightwards arrow with PCC on top space straight R space minus space CH equals straight O
