Polarity & IMFs
True or False? All polar covalent and ionic bonds will form bond dipoles.
What is true
Covalent bonding results from the combination of what types of atoms?
What are Nonmetals
What is two metallic atoms?
CO2
What is linear
All symmetric nonpolar covalent compounds have what IMFs?
What is LDFs only
What type of IMFs are in covalently bonded compounds?
What is London Dispersion Forces, or weak IMFs.
The sea of electrons around metals are caused by?
What is valence orbitals overlapping?
H2O
What is bent?
NH3 vs. PH3
Which boils first?
PH3 because NH3 has hydrogen bonding IMFs
Covalent bonds do not involve charges, therefore the do not involve these types of atoms:
What are Ions
Ionically bonded compounds have __________ intermolecular forces.
What are strong IMFs
Metals can conduct electricity in the ________ phase where as ionic compounds can only conduct when___________.
What is the solid phase & when dissolved in water
NH3
What is trigonal pyramidal
CF4 CBr4 CF2Br2
What compound has the strongest IMFs?
What is CF2Br2 because it has asymmetric bonds, is polar, and will have Dip-Dip.
What causes covalent bonding
What is sharing electrons, equally or unequally
Most Ionically Bonded compounds exist as ____________ in the solid phase.
What are Crystalline Solids
Metallic Bonds do not give or take what to form Ions
What is electron(s)
BF3
What is Trigonal Planar
Without electronegativity values only one of these compounds are nonpolar covalent. Which and why?
F-I F-Br F-F I-Br
What is F-F because whatever fluorine's electronegativity value is, the same number subtracted from itself gives a difference of zero.
Because covalently bonded compounds have _______ IMFs they usually have _________ melting points?
What is weak IMFs & low MPs.
What happens with the electrons in an Ionic Bond?
What is the exchange of electrons between cations and anions, forming opposite charges that attract.
What happens with the electrons in a Metallic Bond?
What would be overlap orbitals to create the "Sea of Electrons" allowing electrons to flow anywhere the want between metal nuclei.
(SO4)2-
What is tetrahedral
