Why does diethyl ether have the smallest dipole?

why does diethyl ether have the smallest dipole compared to Methyl acetate and Butanal? Answer based off of shape, and relative orientation of the polar bonds)

Update:

Dipole moments,

Diethyl ether: 1.15 D

Methyl acetate: 1.72 D

Butanal: 2.72 D

    Diethyl ether is slightly polar because of the bent shape of the molecule. As You can see the polar C-O bonds cancel eachother out leaving the lone pairs to give a slight polarity .
