Intramolecular Forces
Intramolecular Forces
Definition
Intramolecular forces are present within a compound. These forces must be overcome during a chemical change
We can quantify the ability of an atom to gain or lose electrons. Recall that the electronegativity of an atom is a number assigned to an atom that measures its ability to gain electrons.
Electronegativity Differences
- The electronegativity difference between atoms in an ionic compound is generally >= 1.7
- The electronegativity difference between atoms in a covalent compound is generally < 1.7
Types of Compounds
The electronegativity difference between atoms can determine the type of bond
