Intermolecular Forces of attraction

• Whart is the attractive forces present between molecules?

  Intermolecular Forces
• WHAT ARE THE 4 TYPES OF INTERMOLECULAR FORCES?

  LONDON DISPERSION FORCES

  DIPOLE-DIPOLE FORCES

  ION-DIPOLE FORCES

  HYDROGEN BONDING FORCES
• London dispersion forces and dipole-dipole forces are collectively known as van der Waals forces of attraction.
• To whom London Dispersion Forces and Dipole-dipole Forces are named after?

  Johannes van der Waals
• What is the interaction between two oppositely charged particles?

  ion-ion interaction
• Ion-ion interaction is the interaction between two oppositely charged particles.
• what is the other term for ion-ion interaction?

  ionic bonds
• what are charged particles called?

  Ions
• Cations are positively charged particles, while Anion are negatively charged particles
• ion formation is a result of atoms gaining or losing electrons.
• Cations are formed when an atom or molecule loses electrons.

  Anions are formed when an atom or molecule gains electrons.
• What do you call the This type of bond holds together the particles in an ionic compound?

  IONIC BONDS
• Ion-dipole interaction results from the electrostatic attraction of a molecule containing a dipole and an ion.
• What do you call the interaction where in the strength of this kind of IMFA increases as the charge of the ion increases?

  ion-dipole interaction
• In an ion-dipole interaction, The cation is attracted to the partial negative end of the molecule while the anion is attracted to the partially positive end of the molecule.
• The partially positive end of the polar molecule interacts with the

  anion, whereas the partially negative end of the polar molecule

  interacts with the cation.
• The strength of ion-dipole interaction depends on the charge density of the ion.
• Charge density is defined as the actual charge distributed over the total

  volume of the ion.
• the higher the charged density, the stronger the interaction is, while lower charged density has weaker interaction
• Dipole-dipole interactions are attractive forces that are a moderately strong type of IMFA and are present in between polar molecules.
• What do you call an interaction that has an attractive force that is moderately strong type of IMFA and are present in between polar molecules?

  Dipole-dipole interaction
• Dipole-dipole forces are the result of the electrical interactions among dipoles on neighboring molecules.
• What is the term for an interaction where in the partially positive end of one molecule interacts with the partially negative end of a neighboring molecule?

  Dipole-dipole interactions
• Hydrogen bonding is a special kind of dipole-dipole force and one of the strongest types of IMFA.
• What is the term for the special kind of dipole-dipole force and one of the strongest types of IMFA?

  Hydrogen Bonding
• Hydrogen Bonding is an attractive force that exists when hydrogen is bonded to the most electronegative atoms, namely F, O, or N.
• This relatively strong attraction explains why molecules with this type of

  IMFA tend to have high boiling and melting points.
• A hydrogen bond donor is a molecule that provides the hydrogen atom

  participating in a hydrogen bond, while a hydrogen bond acceptor is a molecule that contains the lone pair-bearing electronegative atom.
• What do you call a molecule that provides the hydrogen atom participating in a hydrogen bond?

  Hydrogen Bond Donor
• What do you call a molecule that contains the lone pair-bearing electromagnetic atom?

  Hydrogen Bond Acceptor
• Hydrogen bonding can only be exhibited when one molecule has a hydrogen atom is directly bonded to fluorine, oxygen, or nitrogen atom.
• What are the weakest type of IMFA and are present in between

  all electrically neutral molecules ― polar and nonpolar molecules?

  London Dispersion Forces (LDFs)
• London Dispersion Forces (LDF's) was named after the German-American physicist Fritz London who initially proposed this intermolecular force of attractions.
• London Dispersion Forces are caused by fluctuations in the electron distribution within atoms or molecules.
• This happens when an atom, which is usually nonpolar, becomes polar due to the continual motion of its electrons, resulting in a temporary dipole?

  London Dispersion Forces
• This happens when an atom, which is usually nonpolar, becomes polar due to the continual motion of its electrons, resulting in a temporary dipole.
• All electrically neutral molecules exhibit London dispersion forces

  (LDF).
• An instantaneous dipole is the term given to a molecule when a dipole of uneven charges is created very quickly and randomly in a molecule.
• There are two types of induced dipole forces, ion-induced and dipole-induced.
• what are the two types of induced dipole forces?

  Ion-induced

  Dipole-induced
