Which one of the following exhibits dipole-dipole attraction between molecules?

Question 18 options:

a) AsH3
b) Br2
c) PI3
d) BCl3
e) NO2

1 answer

The correct answer is c) PI3. PI3 exhibits dipole-dipole attraction between molecules because it is a polar molecule with a positive and a negative end. The other options (a) AsH3, (b) Br2, (d) BCl3, and (e) NO2 do not exhibit dipole-dipole attraction between molecules.
