Which Of The Following Intermolecular Forces Plays A Pivotal Role In Biological Molecules?

The answer is (d) Hydrogen bonding.

What types of intermolecular forces are important in biological systems?

The forces that underlie these interactions include van der Waals dispersion and repulsion, hydrogen bonding, and electrostatics. Electrostatic forces are especially important in biological systems because most biomolecules are charged or polar.

How do intermolecular forces affect biological systems?

The physical properties of biological substances depend on the intermolecular forces present. As the strength of forces decreases, so do the melting points, boiling points, and solubility in water. Besides that, the vapor pressure and the solubility in nonpolar solvents also increase.

Which intermolecular forces plays a pivotal role in the unique properties of water?

Water molecules are held together by hydrogen bonds. Hydrogen bonds are a much stronger type of intermolecular force than those found in many other substances, and this affects the properties of water.

What is the role of intermolecular forces in a molecular compound?

Intermolecular forces are the forces that attract molecules or particles to like or unlike molecules or particles. Typically, these forces between molecules form much weaker bonds than those bonds that form compounds.

Why are intermolecular forces important to biological function?

Intermolecular forces are important because they determine the physical properties of substances. Many of the life-sustaining properties of water such as its high heat capacity are a result of the hydrogen bonding capabilities it has and are thus due to intermolecular forces.

What is the role of intermolecular forces?

Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.

Which intermolecular forces depend on the polarizability of molecules?

As polarizability increases, the dispersion forces also become stronger. Thus, molecules attract one another more strongly and melting and boiling points of covalent substances increase with larger molecular mass. Polarazibility also affects dispersion forces through the molecular shape of the affected molecules.

What are the 4 types of intermolecular forces?

12.6: Types of Intermolecular Forces- Dispersion, Dipole–Dipole, Hydrogen Bonding, and Ion-Dipole. To describe the intermolecular forces in liquids.

Which of the following is a type of intermolecular forces present in all molecules?

There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding. Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have LDF.

Which intermolecular force plays a pivotal role in the unique properties of water hydrogen bonding ion dipole force dipole-dipole force dispersion force?

A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule. Hydrogen bonds are important in the properties of water and in certain biological molecules, such as proteins.

What type of intermolecular forces operate in a noble gases B water?

When the noble gases condense, the intermolecular forces that hold the liquid together are induced dipole forces. This type of force occurs when a molecule with a dipole induces a dipole in a non-polar molecule. It is similar to an ion-induced dipole force.

What intermolecular forces are present in CO?

The intermolecular force that is present in CO is London dispersion forces. CO is a highly polar molecule and due to this, it experiences dipole-dipole interaction. CO is a diatomic molecule.

Does molecular geometry affect intermolecular forces?

Figure 11.6 Molecular shape affects intermolecular attraction. Dispersion forces operate between all molecules, whether they are polar or nonpolar. In fact, dispersion forces between polar molecules commonly contribute more to intermolecular attractions than do dipole-dipole forces.

What intermolecular forces increase with increasing molecular mass?

Dispersion forces tend to increase with increasing molar mass.
