Physical Properties of Ethers

Why is ether more volatile than alcohol, even if it has the same molecular formula as alcohol?

$\mathrm{C}-\mathrm{O}-\mathrm{C}$ angle in ether molecule is approximately,

Ethers have lower boiling points than their corresponding isomeric alcohols because of

The $\mathrm{C}–\mathrm{O}–\mathrm{H}$ bond angle in alcohols is slightly less than the tetrahedral angle whereas the $\mathrm{C}–\mathrm{O}–\mathrm{C}$ bond angle in ether is slightly greater because

An ether is more volatile than an alcohol having same molecular formula because

An ether is more volatile than an alcohol having the same molecular formula. This is due to

which Ether is liquid at room temperature:

Which of the following has least boiling point?

An ether is more volatile than an alcohol having the same molecule formula. This is due to

Ether is more volatile than alcohol having the same molecular formula. This is due to

If the boiling point of ethanol (molecular weight$=46$) is $78\mathrm{℃}$, what is the boiling point of diethyl ether? (Molecular weight$=74$)
