alcohols are less volatile than ethers of the same molecular weight, but the two classes of compounds have approximately the same solubility in water because.
a. only alcohols can form hydrogen bonds to water, whereas both compounds can form hydrogen bonds with other molecules of the same type.
b. only ethers can form hydrogen bonds with water, but both compounds can form bonds with other molecules of the same type.
c. both compounds can form hydrogen bonds with water, but only ethers can form hydrogen bonds with themselves.
d. both compounds can form hydrogen bonds with water, but only alcohols can form hydrogen bonds with themseleves.
