Why do all ethers are non polar?
Is it that because the oxygen got two non ligant pair of electrons and thus its geometry tends to be arched?
Thanks.

Ethers aren't non-polar. Most have a fairly low polarity, but THF (Tetrahydrofuran), for instance, has a dipole moment very close to water.
The carbon-oxygen bonds of of ethers are close to the same angle as the carbon-hydrogen bonds of water.
The oxygen is more electronegative than the bonded carbons, so it's always going to have some dipole moment.

| Pdavis is right. However, you might be interested to know that because ethers do not have an H on the O, hydrogen bonding cannot occur. This means it's useful as a solvent when alcohols for example would not be.

The ethers will be non-poler if it's symmetry at the two side of the oxygen of the function group ether.
but most ethers are unsymmetry ,so it might be poler.
