which ones are non polar molecular compounds

a) NBr3
b) CH3I
c) PI3
d) PH3
e) H2S
f) CO2
g) C2H6
h) OF2

Answer 1

Solution.

The molecule can be non-polar, either when there is an equal distribution of electrons between the two atoms of the diatomic molecule, a slight difference in electronegativity or because of the symmetrical arrangement of polar bonds in a more complex molecule.

Thus, non-polar molecules:

b) CH₃I; f) CO₂; g) C₂H₆ ;

Answer: b), f), g).
