The arrows indicate the direction of the force, with attraction and repulsion being oppositely directed
How can the dipole-dipole forces shown in the image be used to explain the properties of polar molecules?
Polar molecules experience dipole-dipole attractions, leading to higher boiling points
Dipole-dipole forces can cause polar molecules to stick together, affecting solubility and other properties
What is a covalent bond?
A chemical bond formed by the sharing of electrons between atoms
Holds atoms together in a molecule
¿Por qué las fuerzas dipolo-dipolo son más fuertes que las fuerzas de dispersión de London?
Porque los dipolos permanentes son más estables
What is the name of the weak force between the atoms in the image?
Intermolecular force
¿Cómo se forman los dipolos instantáneos en las fuerzas de dispersión de London?
Los electrones se mueven al azar
Una región se vuelve temporalmente negativa (δ-)
Otra región se vuelve temporalmente positiva (δ+)
How do the covalent bonds and hydrogen bonds work together to determine the overall shape and properties of the molecule?
The covalent bonds define the internal structure of each molecule, while the hydrogen bonds connect the molecules and influence the overall shape and stability
¿Qué sucede si los dipolos se alinean igual?
Se produce repulsión entre las moléculas
