Intermolecular And Intramolecular Bonds Flashcards
what are intramolecular bonds?
a force that binds the atoms to make a molecule a compound
what do ionic compounds do very well doing and why?
ionic compounds dissolve very well in polar solvents because the polarity of the solvent helps pull apart the ions of the compounds
what are intermolecular bonds
the forces that bind molecules together.
what happens when molecules are attracted slightly to all other molecules are formed or broken a …… is observed
state change
what are 3 types of intermolecular bonds
- London Dispersion Forces
- Dipole-Dipole Forces
- Hydrogen Bonding
what is the weakest of the intermolecular forces (bonds)
London Dispersion Forces
what intermolecular forces (bonds) is in all polar molecule
Dipole-Dipole Forces
what intermolecular forces (bonds) that have a hydrogen atom attached directly to a highly electronegative element including Fonz hydrogen ( Fluorine, Oxygen and Nitrogen)
Hydrogen Bonding
a temporary dipole is attracted to a dipole that has been included by a….
neighbouring molecule
true of false
bonds usually increases in strength as molecules become larger
true
Are individual hydrogen bonds are much weaker than covalent bonds
yes. but however when many hydrogen bonds are acting on each water molecule at the same time, they have a significant effect on the properties of water.
what is the strongest of the intermolecular bonds
molecules like methanol, ethanol, hydrogen fluoride and water with possess hydrogen bonding.
