Misc. Stuffs
What part of a Covalent Compound gets its name changed.
The second element listed in the chemical formula.
Example H2O DiHydrogen, MonOxide
What is a Dipole?
Anything that has two ends with different electric charges.
What range of electronegativity difference does a compound have to be to be considered an Ionic Bond?
at or above 1.7
What range of electronegativity difference does a compound have to be purely covalent/nonpolar?
at .4 and below.
Will CH3OH dissolve in water?
Yes, OH is an alkanol and is always polar
What is the most common type of bonding on Earth and why?
Covalent Bonding because water and carbon dioxide are the two most common things on Earth and are both covalent compounds.
What is a Polar Molecule?
A molecule where one side of the molecule has a different partial charge than another end of the molecule
What does Like - Dissolves - Like mean?
Like substances will dissolve like substances. Polar substances will dissolve polar substances.
What range of electronegativity difference does a compound have to be to be polar?
above .4 and below 1.7
Will SP2 dissolve in water?
No, it is nonpolar
Why do you need to label the charge of transition metals when writing written formulas?
Because transition metals can have different charges. Because of this, if you do not list what charge the atom of the transition metal you are working with you would not know how the transition metal will react with whatever it is combining with.
What is a Polar Bond?
Covalent bond where electrons are not perfectly shared.
What are the two intermolecular forces?
Dipole and Van Der Waal Forces
What are Alkanols?
Alcohols any compound that has an OH- attached to a carbon group.
Will CCl3F dissolve in CBr4?
No, it is polar and CBr4 is nonpolar
What are all the Diatomic Elements?
Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, Bromine
What is a Purely Covalent Bond?
Covalent bond where electrons are shared completely.
800 point question! 400 for each correct part.
What are Van der Waal Forces?
What are dipole forces?
Van Der Waal: The weak forces of attraction between the positive nuclei of one molecule and the negative electrons of a neighboring molecule.
Dipole: (Between polar molecules) the attraction between the partial positive part of one molecule to the partial negative of a neighboring molecule.
What is the only scenario in Ionic Bonding where you would change the name of the anion?
If you have a single element such as carbon into carbide or nitrogen into nitride.
Will CH3F dissolve in water?
Yes, CH3F is polar
What are Polyatomic Ions?
Compounds with a net electric charge.
What does it mean that compounds have "fixed ratios".
Every compound has its own unique ratio of atoms and changing any part of it will change the compound into something new entirely.
H2O = Water, H2O2 = Hydrogen Peroxide
Put the following in order from strongest to weakest:
Metallic bonding, Dipole Forces, Ionic Bonding
Purely Covalent Bonding, Van Der Waal Forces.
Ionic Bonding, Purely Covalent Bonding, Metallic Bonding, Dipole Forces, Van Der Waal Forces
Explain in terms of metallic bonding why metals are good conductors of heat and electricity and why they are very malleable?
In metals the positive nuclei are held together by their attraction to a loosely held sea of negative electrons. Since those electrons are so "loose" it allows heat and electricity to flow through the atom easily. It also makes the metals malleable.
Will CH4 dissolve in water?
No, CH4 is nonpolar so it will not dissolve in water which is polar.
