Chemical Bonding Questions and Answers

What kind of intermolecular forces act between a hydrogen bromide molecule and a chloromethane (CH,CI) molecule? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

It is thought that the strongest intermolecular forces between molecules of NO are Hydrogen bonds Dipole-dipole interactions lonic bonds London forces lon-dipole forces

Which molecules exhibit only London (dispersion) forces? Br₂ CH₂F NH3 BCl3 CH4

Which of the following molecules can hydrogen bond? NF3 H₂S HCI NCl3 NH3

Indicate the bond polarity (show the partial positive and partial negative ends) in the following bonds. (The tail of the arrow indicates the partial positive end of the bond dipole.)

Give the oxidation state of the metal species in each complex. [Co(NH3)5CI]CI: [Ru(CN)(CO)4]-:

Construct the octahedral crystal-field splitting diagram for the metal in each species. V(H₂O)6³+ Fe(CN)64- FeCl63-

Which formula is most likely for a compound of sodium, Na, and phosphorous, P? NaP NaP3 Na3P Na3P3

What is the correct Lewis dot structure for water? H:O:H H:O:H H:O:H H:O:H

Consider the following molecule. Draw the Lewis Structure and use the drawing to fill in the following chart: PF5 Number of Valence e (Whole Structure) Areas of e Density Around Central Atom: Electronic Geometry: # Bonding Areas (Central Atom): # Non-Bonding Areas (Central Atom): Molecular Geometry Bond Angles (Central Atom) Polar Bonds? Polar Molecule? Any Pi (Double/Triple) Bonds? Draw your Lewis Dot:

Unlike soap, which is ionic, some liquid laundry detergents are neutral molecules. Explain how the following molecule behaves like soap and cleans away dirt. The molecule serves as a catalyst so the dirt and water can bond directly. The molecule ionizes readily. The molecule displaces the dirt by bonding to the clothing. The molecule has a highly polar end and a nonpolar tail.

Initial amount (at t=0), A. (The simulation uses "N=_ Time elapsed, t (In seconds, what time did you pause the simulation?) "for the amount at a given time) Amount after time has passed, A (The simulation uses "N=_ "for the amount at a given time) h = t-log (0.5) (A) log 400 nuclei 35 43 This equation is the half-life equation (one version of it), but it has already been algebraically rearranged to solve for the half-life, h. 1) Calculate the half-life of the simulated isotope using A. A. and t from your simulation. Units for half-life should be in seconds for this simulation, and the number should be reasonable (i.e., a positive value less than 100). Show your work. (4 pts)

Based on general ranking of intermolecular forces, what is the strongest intermolecular force between CO₂ molecules? a. dispersion b. dipole-dipole c. H-bonding d. dipole-induced dipole

To balance a chemical equation correctly when the reactants and products are known, you must adjust the formulas of the substances adjust the subscripts in the formulas equate the number of molecules on each side equate the number of atoms on each side

An isotope, 15x7 has an atomic number of 7 and a mass number of 15. Therefore X is an isotope of nitrogen X has 7 neutrons per atom X has 8 protons per atom X is an isotope of phosphorus
