To the atoms of which element are the electron pairs displaced in SO2, NH3, CS2 and CH4?

In SO2 – to oxygen, since its electronegativity is higher than that of sulfur
In NH3 – to nitrogen, since its electronegativity is higher than that of hydrogen
In CS2 – to sulfur, since its electronegativity is higher than that of carbon
In CH4 – to carbon, since its electronegativity is higher than that of hydrogen
