WebMay 18, 2024 · 1 Answer. (Ignore the stuff written with pen; I have a habit of taking notes when reading) PCC is taking two hydrogen atoms – one from the carbon atom attached to the -OH group and the other one from the -OH group itself, and then making a C=O double bond. Methanol has both of these. So, PCC should be able to oxidise it to formaldehyde.
