The following support Valence Shell Electron Pair Repulsion (VPESR) Theory EXCEPT one:
Molecules adjust their shapes to keep the pairs of valence electrons as far as possible
Two electron pairs have linear arrangement and are separated at 180 degrees
Three electron pairs gave triangular planar shape and are separated at 120 degrees
Four electron pairs have tetrahedral shape and are separated at 109 degrees
Determine the formula of formal charge.
Formal charge = (number of shared electrons) - (number of valence electrons) - (number of unshared electrons)
Formal charge = (number of shared electrons) - (number of shared electrons) - (number of valence electrons)
Formal charge = (number of valence electrons) - (number of unshared electrons) - (number of shared electrons)
Formal charge = (number of unshared electrons) - (number of shared electrons) - (number of valence electrons)
Molecular Geometry looks at the arrangement of atoms. Electron Domain Geometry considers the effect of the nonbonding domains to the shape of the molecule/ion.

A completely polar bond, or ionic bond, occurs when the difference between electronegativity values is large enough that one atom actually takes an electron from the other.
True
False
How do you determine the polarity of a covalent bond?
Taking the sum between the electronegativity of the atoms
Taking the difference between the electronegativity of the atoms
Taking the sum between the atomic number of the atoms
Taking the difference between the number of electrons of the atoms
Which of the following is true about Pauling Scale of Electronegativity?
0.0 - o.4 = nonpolar covalent bond
0.3 to 1.6 = polar covalent bond
equal to or greater than 1.7 = ionic bond
0.0 - o.4 = polar covalent bond
0.3 to 1.6 = nonpolar covalent bond
equal to or greater than 1.7 = ionic bond
0.0 - o.4 = nonpolar covalent bond
0.4 to 1.7 = polar covalent bond
equal to or greater than 1.7 = ionic bond
0.0 - o.4 = polar covalent bond
0.4 to 1.7 = nonpolar covalent bond
equal to or greater than 1.7 = ionic bond
Differentiate Intermolecular Forces and Intramolecular Forces. Which of the following are true?
Intermolecular forces - the attractive forces within elements of a compound
Intramolecular forces - the attractive forces between neighboring particles.
Intermolecular forces - strong because charges are closer together.
Intramolecular forces - weak because charges are far from each other.
Intermolecular forces - the attractive forces between neighboring compounds.
Intramolecular forces - the attractive forces within elements of a compound
Intermolecular forces - it can be ionic, covalent, or metallic.
Intramolecular forces - includes dipole-induced dipole interaction, ion-dipole attraction, dispersion forces, and others.
Hydrogen bonding is weaker than dispersion forces. Dipole-induced dipole interaction is stronger than dispersion forces.
Both statements are true.
Both statements are false.
Statement 1 is true. Statement 2 is false.
Statement 1 is false. Statement 2 is true.
Cohesion is stronger than adhesion. Cohesion occurs between molecules of a liquid while adhesion occurs between liquid and solid surface.
Both statements are true.
Both statements are false.
Statement 1 is true. Statement 2 is false.
Statement 1 is false. Statement 2 is true.
Higher temperature means higher kinetic energy. Higher kinetic energy means higher viscosity.
Both statements are true.
Both statements are false.
Statement 1 is true. Statement 2 is false.
Statement 1 is false. Statement 2 is true.
The stronger the intermolecular force, the higher the boiling point. The higher the boiling point, the less viscous a substance is.
Both statements are true.
Both statements are false.
Statement 1 is true. Statement 2 is false.
