What is the inorganic compound that can be considered the structural basis for alcohols and
ethers? Discuss two ways in which the physical properties of alcohols and ethers are similar to
properties of this compound. Answer: Alcohols and ethers can be considered to be derivatives
of water. Similar physical properties include:
Polarity: Water is a very polar molecule; alcohols and ethers also display polarity.
Boiling point: Water has a higher boiling point than predicted on the basis of its molar mass.
Alcohols also share this characteristic, but ethers do not.
Solubility: Water is miscible with other polar liquids; alcohols and ethers of low molar mass are
miscible with water and with each other because of their polarity.
