Many hand sanitisers contain alcohols such as ethanol and propanol.
The table shows the names and formulae of the first four alcohols.
| Name of alcohol | Formula |
|---|---|
| methanol | CH3OH\mathrm{CH_{3}OH}CH3OH |
| ethanol | X |
| propanol | C3H7OH\mathrm{C_{3}H_{7}OH}C3H7OH |
| Y | C4H9OH\mathrm{C_{4}H_{9}OH}C4H9OH |
State the functional group that is present in all alcohols.
Use the table to answer these questions.
