Question

Are dipole-dipole forces or London dispersion forces stronger?

Answer 1

Intermolecular forces are the forces that mediate interplay among molecules, consisting of forces of enchantment or repulsion which act among atoms and different varieties of neighboring particles, e.g. atoms or ions. In massive molecules which have a massive range of electrons (this means that the electron cloud may be distorted to a more degree).

Complete Answer:
Both dipole-dipole forces and London dispersion forces are intermolecular forces, which suggest that they are each forced among one-of-a-kind molecules. Dipole-dipole forces arise while the molecules are polar, and the high-quality aspect of 1 molecule is barely interested in the bad aspect of some other.
Because they want dipoles to exist, they are most effective found in polar molecules. London dispersion forces arise while one molecule, which is usually non-polar at the beginning, has a "brief dipole." That's while electrons show up to be greater on one aspect of the molecule. This creates a "caused dipole" in some other molecule. London dispersion forces are the sights among the brief dipole and the caused dipole. They do not require dipoles, so London dispersion forces may be found in each polar and non-polar molecule. Because London dispersion forces are brief, they are weaker than the everlasting dipole-dipole sights. However, London dispersion forces may be pretty robust sometimes!
In massive molecules which have a massive range of electrons (this means that the electron cloud may be distorted to a more degree), London dispersion forces may be so robust that the molecules are beverages or solids at room temperature.

Note:
Non-polarity tells us that the most effective intermolecular forces it has are London dispersion forces. In n-pentane: The molecule could be very massive, this means that now no longer most effective are there greater London dispersion forces present, however additionally more potent London dispersion forces. This permits n-pentane to be liquid at room temperature.
