Chapter 6.3: Interactions Involving Polar Molecules Vocab Cards Flashcards
Interactions Involving Polar Molecules (13 cards)
Dipole-Dipole Interaction
Attraction between areas of polar molecules with partial charges of different sign (+ or -)
Organic Compounds
Compounds that contain carbon.
Functional Group
A group of atoms in an organic compounds molecular structure that give the organic compounds physical and chemical properties.
Carbonyl Group
Functional Group consisting of a carbon atom double bonded to an oxygen atom.
Ketone
Organic Compound with a carbonyl group bonded to two other carbon atoms.
Hydrogen Bond
A strong dipole-dipole interaction between a hydrogen atom bonded to an N, O, or F atom and the hydrogen atom’s bond to another N, O, or F atom’s lone pairs from another molecule.
Hydroxyl Group
Functional Group consisting of an oxygen atom single bonded to a hydrogen atom.
Alcohol
Organic Compound whose hydroxyl group is bonded to a carbon atom; the carbon atom is not bonded to any other functional group.
Ether
Organic Compound with an oxygen atom single bonded to two carbon atoms.
Ion-Dipole Interaction
An attractive force between an Ion and a molecule that has a permanent dipole.
Sphere of Hydration
A Cluster of H2O molecules that surround an ion in a solution where H2O is the solvent; includes the inner sphere of hydration and the outer sphere of hydration.
Inner Sphere of Hydration (ISH)
Part of the sphere of hydration where the H2O molecules orient their oxygen atom to the cation(s) of the ion and the H2O molecules’ H atoms are oriented to the anion(s) of the ion; the number of H2O molecules in the ISH can vary.
Outer Sphere of Hydration (OSH)
Surrounds the H2O Molecules in the ISH and forms hydrogen bonds with the H2O molecules in the ISH. This sphere is surrounded by bulk H2O molecules that are hydrogen bonded to each other and the H2O molecules in the OSH.
