Intramolecular Forces vs Intermolecular Forces

Intermolecular Forces Notes. Intermolecular Forces o Intermolecular Forces: attraction between molecules o Much weaker than chemical bonds.

Boiling Point of Molecules - How strong molecules are interacting with each other - The larger the dipole moment, the stronger the interaction ++ --

2.4 Intermolecular Forces

Electronegativity and Polarity.  Describe how electronegativity is used to determine bond type.  Compare and contrast polar and nonpolar covalent bonds.

Types of Intermolecular Bonds

Intermolecular Forces. How are molecules held together? There are two types of attraction in molecules: ◦ Intramolecular forces ◦ Intermolecular forces.

Liquids Properties of liquids are similar to solids’, and way different from gas properties density compressibilities enthalpy changes attractive forces.

Phase Equilibriums.

Unit 6: Covalent Bonding Intermolecular Forces. Intra- versus Inter- molecular Forces Intra (means “within”) and refers to the forces that hold atoms.

Bonding Types & Properties Formative. What type of bond and what type of electron interaction occurred in the compound CaCl 2 ? 1.Ionic – Transferred.

Unit 4A ACS Chemistry in the Community Sixth Edition.

Chemical bonding Bonding Chemical bond – the transfer or sharing of electrons Ionic bond- the transfer of electrons Covalent bonding – the sharing of electrons.

SECTION 2-1 CONT. Bonding. TYPES OF CHEMICAL BONDS  Bonds involve the electrons in an atom.  1. Ionic Bonds Electrons are transferred from one atom.

3.4 INTERMOLECULAR FORCES. INTERMOLECULAR FORCE An attraction between molecules Weaker than the forces within the molecules.

INTERMOLECULAR FORCES (bonds) Occur between molecules Weaker than intramolecular forces.

Polar Bonds and Molecules Chapter 8.4

Polar Bonds and Molecules. Bond Polarity  Not all covalent bonds are equal in their sharing of electrons  A lot depends on the type of atoms involved.

Polar Bonds and Molecules Notes. Bond Polarity The bonding pairs of electrons are pulled in a tug-of-war between the nuclei of the atoms sharing the electrons.

Valence Shell Electron Repulsion Theory (VSEPR)

Intermolecular Forces

Solubility: Molecular Polarity. How do molecules stay together?

Intermolecular Forces Chemistry 11 Ms. McGrath. Intermolecular Forces The forces that bond atoms to each other within a molecule are called intramolecular.

Why do some solids dissolve in water but others do not? Why are some substances gases at room temperature, but others are liquid or solid? The answers.

What You Need to Know For Unit A: Bonding. General Outcome 1 Students will describe the role of modelling, evidence and theory in explaining and understanding.

Why do some solids dissolve in water but others do not? Why are some substances gases at room temperature, but others are liquid or solid? The answers.

 shared bonding electrons pairs are pulled (as in a “tug-of-war”) between atoms  results in an equal or unequal sharing.

Bond Types You will be able to identify the type of bond between atoms based upon their EN.
