Diethyl ether, and 1-butanol are similar in size (number of electrons), therefore, their boiling points will be determined by polarity. Diethyl ether has two polar C-O bonds. 1-butanol also has two polar bonds (C-O and O-H), but the O-H bond is more polar than the C-O bond, making 1-butanol more polar than diethyl ether and giving it a higher boiling point. Diethyl ether has weaker intermolecular forces of attraction and therefore a lower boiling point.
Diethyl ether can be formed from alcohol by intermolecular dehydration of alcohols. When alcohol is heated with conc. H2SO4 at 140*C, diethyl ether is obtained. CH3CH2OH + H2SO4 -----------> CH3CH2OCH2CH3 ( diethyl ether) It must be noted that at high temp (180*C) the reaction is elimination which form alkene.
Yes, it can. Hydrogen bonding is an intermolecular force, that is, it occurs between molecules and is specific to Hydrogen and either Fluorine, Oxygen or Nitrogen. The molecular formula of diethyl ether is C2H5-O-H5C2. The Oxygen in the middle of the molecule is likely to form bonds with Hydrogen from other diethyl ether molecules, and hence, diethyl ether can form hydrogen bonds.
