Diethyl ether or butyl alcohol has the higher boiling point?

Question

Diethyl ether or butyl alcohol has the higher boiling point?

Answer 1

Which has the greater BP?

C-C-O-C-C or C-C-C-C-OH

Why, it would be the alcohol.  The alcohol has hydrogen bonding (plus London dispersion forces) which will produce more intermolecular attraction than the London dispersion forces alone which are found in the ether.

Answer 2

Butyl alcohol has the higher boiling point, of course

Cause:

It has hydrogen bond, which will hold the molecules together, thus make it harder to separate them (boiling is heating molecules so that the "move out" from the liquid)).

On the other hand:

diethyl ether has no hydrogen bond, which make it easier for molecules to "break out" when heated, so it would have a low boiling point.

i don't think van der Waals force (London dispersion force) have anything to do. Boiling is just about the bond between molecules of the substances (or so I think)

Answer 3

Butyl alcohol has the highest b.p. Although there exist a bulky group which is (CH3)C , in the structure of butyl alcohol but it can get the chance to form  H-bond to be associated & to upgrade the b.p itself.

Otherwies there is no scope for H-bond formation in the case of diethyil ether. It has only a so weak inter molicular vanderwall attraction force for which the probability for association of the atoms in the former is very small with respect to the later.

this is the main fact for why the (CH3)C-OH has the greater b.p than the H5C2-O-C2H5.
