Answer #1

a) sulfur tetrafluoride

SF4 --> Sulfur has extra electron pairs, therefore, expect electron repulsion of the F4 atoms, then

there is a dipoile formation, which is a POLAR molecule

b) dihydrogen monoxide

H2O; it is known for its 2 lone pairs on th eoxygen, then expect this to have bent shape

that is, dipole molecule, which isPOLAR

c) carbon disulfide

CS2 --> this is linear, electron pairs cancel each other force so there are no dipols, that is, nonpolar
