Answer:
c. D represents ion-dipole forces, which are stronger than the force represented by C.
Explanation:
From the map:
D represents ion-dipole forces.
C represents H-bonding forces.
Ion dipole forces are the forces between a charged ion and polar molecule and it is electrostatic in nature.
Hydrogen bonding is a special case of dipole-dipole forces and it is present when there is a H=atom bonded to an electronegative atom such as: N, O, and F.
Ion dipole forces is stronger than that of H-bonding.
so, the right choice is:
c. D represents ion-dipole forces, which are stronger than the force represented by C.
