Question
State physical properties of ethers.
✓
Answer
(1) Dimethyl ether and ethyl methyl ether are gases. Other ethers are colourless liquids with pleasant odour.
(2) Lower ethers are highly volatile and highly inflammable substances.
(3) Boiling points of ethers show gradual increase with the increase in molecular mass.
| Ether | B.P./K |
| $CH _3- O - CH _3$ | 248 |
| $C _2 H - O - CH _3$ | 284 |
| $C _2 H _5- O - C _2 H _3$ | 308 |
(4) The solubility/miscibility of ethers in water is similar to that of alcohols of comparable molecular mass.
