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
