Explanation:

Ethene is an organic molecule created of two carbon atoms, join by a twin bond, and four hydrogen atoms.

You are watching: What type of intermolecular force causes the dissolution of nacl in water?

*

Ethene, favor all molecules, exhibits London dispersion forces. This molecule, however, has no net dipole moment, therefore it will certainly not exhibition dipole-dipole attraction. Also, even though it consists of hydrogens, that does not exhibit hydrogen bonding. To exhibition hydrogen bonding, the hydrogen atoms have to be fastened to much more electronegative atoms, namely nitrogen, fluorine, or oxygen. Finally, ionic bonding is only present in ionic compounds, not organic compounds.

Explanation:

Ionic bonds are the strongest type of bonds, complied with by covalent bonds, hydrogen bonds, and also lastly, van Der waals forces.


Explanation:

Although the two molecules seem similar in structure, proponol has a higher boiling allude due come the hydrogen bonding enabled by its alcohol group. This creates a solid intermolecular force, and extra energy is subsequently needed to break these bonds, bring about a greater boiling point.

System pressure and also temperature are concerned boiling point, but are not necessary when comparing the nature of 2 molecules.


Explanation:

Ionic and also covalent bonds are not intermolecular forces;

Ion-dipole>hydrogen bonds>dipole-dipole>van Der Waals forces


Explanation:

This is butanol. The is one alcohol; oh is the prime example of hydrogen bonding, i m sorry is the strongest intermolecular force.


Explanation:

Ion-dipole forces are the strongest of the intermolecular forces.

Hydrogen bonding is a particular term for a an especially strong dipole-dipole interaction in between a hydrogen atom and a an extremely electronegative atom (oxygen, fluorine, or nitrogen). However, hydrogen bonds room still not as strong as ion-dipole interactions.

In stimulate from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Ionic bonding is more powerful than any type of of the given intermolecular forces, however is itself no an intermolecular force. Ionic bonds are a irreversible chemical connection between two atoms, vice versa, intermolecular pressures as a an ext transient and temporary attraction in between independent molecules.


Explanation:

Formaldehyde, choose all atoms and also molecules, will certainly have an extremely weak London dispersion forces created as electrons change within the electron cloud. Since it possesses a permanent dipole (based on the polarized carbon-oxygen bond), formaldehyde also exhibits dipole-dipole interactions. The does not, however, exhibition hydrogen bonding, due to the fact that no hydrogens space attached to oxygen (or various other electronegative atoms like nitrogen or fluorine).


Explanation:

There is a key difference between atomic bonds and intermolecular forces. Metallic bonds, ionic bonds, and also covalent bonds are all atomic bonds. This means that they are usually stable and fairly irreversible. An atomic bond will readjust the identity of a link by including an atom come the structure.

Intermolecular forces, in contrast, are much more transient and also less stable. These attractions room constantly broken and reformed as molecules relocate around. Hydrogen bonds, dipole-dipole interactions, and also van der Waals pressures (London dispersion forces) space some common examples of intermolecular forces. Intermolecular pressures will never readjust the identity of the molecule and also cannot be provided to add atoms come a compound.


Explanation:

There is a an essential difference in between atomic bonds and intermolecular forces. Ionic bonds and also covalent bonds room atomic bonds, meaning they room intramolecular. This means that castle are typically stable and fairly irreversible. An atom bond will readjust the identity of a link by including an atom to the structure.

Intermolecular forces, in contrast, are much more transient and also less stable. This attractions room constantly broken and reformed together molecules move around. Hydrogen bonds, dipole-dipole interactions, and also van der Waals pressures (London dispersion forces) are some typical examples of intermolecular forces. Intermolecular forces will never readjust the identification of the molecule and also cannot be offered to include atoms come a compound.

The the strongest intermolecular pressure is hydrogen bonding, i m sorry is a details subset the dipole-dipole interaction that occur when a hydrogen is in near proximity (bound to) a highly electronegative aspect (namely oxygen, nitrogen, or fluorine). The hydrogen bring away on a partial optimistic charge and the electronegative atoms takes top top a partial negative charge.
