`=>` The `C-O` bonds in ethers are polar and thus, ethers have a net dipole moment.
`=>` The weak polarity of ethers do not appreciably affect their boiling points which are comparable to those of the alkanes of comparable molecular masses but are much lower than the boiling points of alcohols as shown in the following cases :
`color{red}(tt((text(Formula) , undersettext(n-Pentane)(CH_3(CH_2)_3CH_3), undersettext(Ethoxyethane)(C_2H_5-O-C_2H_5) , undersettext(Butan-1-ol)(CH_3(CH_2)_3-OH)), (b.p//K, 309.1, 307.6, 390)))`
`=>` The large difference in boiling points of alcohols and ethers is due to the presence of hydrogen bonding in alcohols.
`=>` The miscibility of ethers with water resembles those of alcohols of the same molecular mass.
● Both ethoxyethane and butan-1-ol are miscible to almost the same extent i.e., `7.5` and `9` g per `100` mL water, respectively while pentane is essentially immiscible with water.
● This is due to the fact that just like alcohols, oxygen of ether can also form hydrogen bonds with water molecule as shown in fig.
