Answer
See the answer below.
Work Step by Step
a) Polar, diatomic with different atoms.
Oxygen is more electronegative than carbon so it's the negative end.
b) Nonpolar, polar bonds with the same difference in electronegativity in a symmetrical geometry (trigonal planar).
c) Nonpolar, polar bonds with the same difference in electronegativity in a symmetrical geometry (tetrahedral).
d) Polar, polar bonds with the same difference in electronegativity in an asymmetrical geometry (trigonal pyramidal).
Phosphorus is less electronegative than chlorine so it's the positive end while chlorine is the negative end.
e) Nonpolar, polar bonds with the same difference in electronegativity in a symmetrical geometry (tetrahedral).
