Step-by-step explanation:
Ответ:
A represents London dispersion forces, which are weaker than the force represented by B.
Explanation:
From the scheme, A represents London-dispersion forces and B represents H-bonding forces.London Dispersion Forces : Intermolecular forces exist between non-polar molecules. They are very weak forces. Thought to be arise from the motion of electrons.
H-bonding: It is a special type of dipole-dipole interaction between the H-atom in a polar bond such as N-H, O-H, F-H and an electronegative atom such as nitrogen, oxygen and fluorine.
It is clear that H-bonding is stronger than London-dispersion.
So, the right choice is:
A represents London dispersion forces, which are weaker than the force represented by B.
