butan-1-ol<br />
pentan-1-ol<br />
methanoic acid<br />
ethanoic acid<br />
propanoic acid<br />
benzoic acid<br />
salicylic acid<br />
All harmful to varying extent by<br />
ingestion, inhalation and by skin<br />
absorption.<br />
Methanol is more toxic than the<br />
others.<br />
Methanol, ethanol and propan-1-ol<br />
are highly flammable and the others<br />
are flammable.<br />
The three aliphatic acids are<br />
corrosive.<br />
Methanoic acid is quite toxic and<br />
ethanoic acid is flammable.<br />
The two aromatic acids are very<br />
irritating to the skin.<br />
concentrated sulphuric acid Causes severe burns to eyes and<br />
skin.<br />
Notes<br />
This experiment should be carried out in a well-ventilated room.<br />
