Intermolecular Forces

This is the weakest among intermolecular forces.

• Dipole-dipole Interaction

• London Dispersion Force

• Hydrogen Bond

• Ion-dipole Interaction

What is the definition of an Anion?

• A positively charged ion.

• A molecule with no charge.

• A neutral atom.

• A negatively charged ion.

Answer explanation

The dispersion is caused by _________.

• Covalent Bonding

• Polarization

• Ionic bonding

• Magnetism

This is an intermolecular force of attraction that occurs between partially positive and partially negative ends.

• Dipole-dipole Interaction

• Ion-dipole Interaction

• London dispersion force

• Hydrogen Bond

The dipole-dipole interaction contains how many percent of the strength of ionic bonds?

• 1%

• 2%

• 3%

• 4%

This type of intermolecular force arise from the interaction between an ion and polar molecule.

• Hydrogen Bond

• Dipole-dipole Interaction

• Ion-dipole Interaction

• London Dispersion Force

What does Cation means?

• Positively charge ion

• Negatively charge ion

• Neutral

• No charge ion

The strength of the hydrogen bond is the reason for the high melting and boiling points of;

• water, methanol, and alcohols such as ammonia.

• methanol, alcohols, and ammonia such as water.

• water, ammonia, and methanol such as alcohols.

• water, ammonia, alcohols such as methanol.

This type of Intermolecular force is important in holding together the complementary nitrogenous basis in DNA, as well as the formation of protein structures.

• Hydrogen Bond

• Ion-dipole interaction

• Dipole-dipole interaction

• London dispersion force

This type of Intermolecular force is exist in all substances including inert gases.

• London dispersion force

• Dipole-dipole interaction

• Ion-dipole interaction

• Hydrogen Bond
