POLARITIassess the polarity of bonds see how theycome together to find polarity of molecule

how to find bond polarity comes down to

electronegativity

Oy

dipole moments St S2 interchangeable

draw Lewis structure so you find us EPR

geometry

determine each bond's polarity

using VSEPR from step yousum up each bond's dipole moment
