Why does the boiling point of a series of ethers decrease as the molecular weight of the ethers increase?

A) Because of increased hydrogen bonding
B) Because of decreased van der Waals interactions
C) Because of increased molecular intertwining
D) It doesn't; rather the boiling points increase as the molecular weight increases.

Ethers

A class of organic compounds characterized by an oxygen atom connected to two alkyl or aryl groups, widely used as solvents and in the production of pharmaceuticals and chemicals.

Boiling Point

The boiling point is the temperature at which a substance transitions from a liquid to a gas (vaporizes) at a given pressure, distinctive for each substance.

Molecular Weight

The sum of the atomic weights of all atoms in a molecule, indicating the size of the molecule.
