i think $OCl_2$ has a bent shape, you can check this using vsepr. Alkanes are non-polar, just like $CH_4$ is non-polar. Acetone is polar C-O bond.

Yeah I know, but the dipole moment is less than 0.5 regardless

of acetone?

The net dipole moment?

bocoz of the electronegative difference between O and Cl :) 
O is more electronegative than the Cl :) so the Oxygen attracts the bonding electrons towards itself and gets partial -ve charge and that of Cl get partial +ve charge :) as result charge seperation which leads to polarity|dw:1387339146732:dw|
