Bondings and Forces Flashcards
Covalent bonds are created between what type of elements?
Non-metallic elements including carbon and hydrogen and the same types of elements such as O2.
Hydrogen bonds are formed between which elements?
Fluorine, oxygen and nitrogen only.
What is special about dispersion forces?
Dispersion forces occur between all molecules and are the only forces between non-polar molecules.
What intermolecular force holds polar molecules only?
Dipole-dipole.
What are intermolecular forces?
These are forces between molecules such as hydrogen bonds, dipole dipole forces and dispersion forces.
What are intramolecular forces?
These are forces inside the molecule such as covalent, ionic and metallic.
What bonding occurs between metallic elements?
Metallic bonds
Are intermolecular bonds stronger than intramolecular?
No, intramolecular bonds such as covalent bonds are stronger than intermolecular bonds such as hydrogen bonds.
What is the order of intermolecular forces from weakest to strongest?
Dispersion forces, dipole dipole then hydrogen bonds.
What type of force is a hydrogen bond?
Hydrogen bonds are a type of dipole dipole force.
What bonding is created between a metal and non-metal?
Ionic bonding which is the electrostatic attraction between cations (positive with ‘t’) and anions (negative without ‘t’).
