The two complementary strands of DNA are held together primarily by hydrogen bonds between the nitrogenous bases (adenine with thymine, and guanine with cytosine). Additionally, hydrophobic interactions and van der Waals forces contribute to the stability of the double helix structure. These interactions allow the strands to remain tightly coiled while maintaining the specificity of base pairing.

What is it when atoms combine the force of attraction that holds the together?
Intermolecular forces
What is stronger intermolecular or intra?
Intra-molecular forces are stronger than intermolecular forces because intra-molecular forces act within a molecule to hold its atoms together, such as covalent bonds. Intermolecular forces act between molecules and are generally weaker, like van der Waals forces or hydrogen bonding.
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
Intermolecular forces that must be overcome to convert H2Se to gas?
The intermolecular forces that must be overcome to convert H2Se (hydrogen selenide) to gas are London dispersion forces and dipole-dipole interactions. These forces hold the H2Se molecules together in the liquid state. As energy is added to the system, these intermolecular forces weaken, allowing the molecules to overcome the attractive forces and transition into the gaseous state.
What is the intermolecular ammonia and ammonia?
The intermolecular forces are hydrogen bonding.
What hold atoms together inside a molecule?
intermolecular forces examples are dispersion forces
What is name of the force that holds the nucleus of an atom together?
intermolecular forces
What is it when atoms combine the force of attraction that holds the together?
Intermolecular forces
What forces hold molecular together?
London dispersion forces (also known as van der Waals forces) hold molecular solids together. or Intermolecular forces
How are intermolecular forces different from forces that bind atoms together into molecules?
1. Intermolecular forces are the forces between molecules, while chemical bonds are the forces within molecules. 2. Chemical bonds combine atoms into molecules, thus forming chemical substances, while intermolecular forces bind molecules together. 3. Chemical bonding involves the sharing or transferring of electrons, while intermolecular forces do not change the electron stucture of atoms. 4. Intermolecular forces hold objects together, while chemical bonds hold molecules together.
Are the intramolecular forces in paradichlorobenzene stronger than the intermolecular forces?
Yes, intramolecular forces such as covalent bonds in paradichlorobenzene are stronger than intermolecular forces like van der Waals forces between molecules. Intramolecular forces hold atoms within a molecule together, while intermolecular forces act between molecules.
What is the relationship between the strength of the intermolecular forces and boiling point?
The strength of intermolecular forces is directly related to the boiling point of a substance. Substances with stronger intermolecular forces require more energy to break those forces, leading to a higher boiling point. Conversely, substances with weaker intermolecular forces have lower boiling points.
What type of intermolecular forces hold morphine molecules together?
hydrogen bonds
What is stronger intermolecular or intra?
Intra-molecular forces are stronger than intermolecular forces because intra-molecular forces act within a molecule to hold its atoms together, such as covalent bonds. Intermolecular forces act between molecules and are generally weaker, like van der Waals forces or hydrogen bonding.
Is dipole-dipole forces an intramolecular force?
No, dipole-dipole forces are intermolecular forces - they occur between different molecules. Intramolecular forces, on the other hand, act within a single molecule to hold its atoms together.
What is the correct order of states from least to greatest intermolecular forces of attraction?
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
