A laboratory record gives the information shown.
| Starting material | Reagent | Condition |
|---|---|---|
| propan-1-ol, C3H7OH\mathrm{C_3H_7OH}C3H7OH | acidified potassium manganate(VII) | warmed |
The organic product is compared with four carboxylic acid reference samples.
| Reference sample | Relative formula mass |
|---|---|
| W | 46 |
| X | 60 |
| Y | 74 |
| Z | 88 |
Relative atomic mass (ArA_rAr): H = 1.0 C = 12.0 O = 16.0
How does the relative formula mass of the oxidation product compare with the reference samples?
It is the same as that of reference sample W.
It is the same as that of reference sample X.
It is the same as that of reference sample Y.
It is the same as that of reference sample Z.
