Starting material is benzyl alcohol which is oxidized into benzaldehyde.
1H NMR :
Delta 10.0 (s, 1H) indicates aldehyde proton.hDelta 8.0-7.5 (m, 5H) indicates phenyl group.
In NMR oxygen attached protons around delta 4.0 disappeared indicates oxidation.
Both IR and IH NMR confirms benzyl alcohol oxidation to benzaldehyde.
In IR OH stretch at 3500 to 3000 cm-1 is absent and carbonyl stretch at 1700 cm-1 present indicates oxidation.
