Which compound has the strongest hydrogen bonding between its molecules?

The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding.

Which compound has hydrogen bonding between its molecules?

Explanation: Hydrogen bonding occurs between a hydrogen atom and an atom that has a high electronegativity such as fluorine, oxygen, or nitrogen. In this case, the only compound that exhibits hydrogen bonding is water, which has a hydrogen bonded to an oxygen atom.

Which hydrogen bond is the strongest?

So fluorine has maximum electronegativity and minimum atomic size.

Why does hydrogen bonding occur?

Why Hydrogen Bonds Form

The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom. … The result is that the hydrogen atom carries a weak positive charge, so it remains attracted to atoms that still carry a negative charge.

Which compound has the strongest intermolecular forces?

The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).

Which is the least bond angle?

Bond angle in BeF2 is 180∘ because it is a linear molecule. Due to the presence of two lone pairs in H2O, H O-H has the least bond angle.

What makes a strong hydrogen bond?

Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.

How much energy does it take to break a hydrogen bond?

The energy required to break the O—H covalent bond (the bond dissociation energy) is about 111 kcal/mole, or in more proper SI units, 464 kJ/mole.

How do you know when hydrogen bonding occurs?

In order for a hydrogen bond to occur there must be both a hydrogen donor and an acceptor present. The donor in a hydrogen bond is usually a strongly electronegative atom such as N, O, or F that is covalently bonded to a hydrogen bond.

What is the difference between a covalent bond and a hydrogen bond?

Covalent bond is a primary chemical bond formed by the sharing of electron pairs. Covalent bonds are strong bonds with greater bond energy. Hydrogen bond is a weak electrostatic attraction between the hydrogen and an electronegative atom due to their difference in electronegativity.

What are the types of hydrogen bonding?

Types of Hydrogen Bonding

  • The Intramolecular Hydrogen Bonding.
  • The Intermolecular Hydrogen Bonding.

What is the weakest type of intermolecular force?

London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent—polar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are.

What are the 3 intermolecular forces from weakest to strongest?

There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals’ forces.

What is the weakest IMF?

The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
