Consider the molecules — BrF5. A. Draw the best Lewis structure for this molecule. Label any atoms with nonzero formal charge. B. Label each bond angle. As part of your answer be sure to include if it is more or less than the ideal bond angle.  C. What is the electron geometry around the bromine atom? D. Are the bonds in the molecule polar? E. Is the overall molecule polar? — CH2 F2 . A. Draw the best Lewis structure for this molecule. B. Label each bond angle. Answers for A-D here: C. Redraw the shape of the molecule. Draw all dipoles. D. Is the overall molecule polar? — Consider the molecule CH2 CF2 . A. Draw the best Lewis structure for this molecule. B. Label each bond angle. C. Redraw the shape of the molecule (according to the exacting specifications of your instructor). Draw all dipoles. D. Is the overall molecule polar?

Use Lewis theory to determine the formula for the compound that forms between the two elements listed. Express your answer as a chemical formula. A.)  Ca and N   B.)  Mg and I   C.)  Ca and S   D.)  Cs and F

Draw the Lewis structures of the neutral atom of Nitrogen and the ion of Nitrogen. Determine also the number of electrons gained or lost in forming an ion.                          ------------------IN SHORT------------------- Draw the Lewis Structures for:  1. Neutral Atom of Nitrogen 2. Ion of Nitrogen      - Determine also the number of electrons gained or lost in forming an ion. NOTE : The Answer must be two different Lewis Structures, one for the Neutral Atom of Nitrogen and one for the Ion of Nitrogen. Both are different from each other so the answer should have 2 forms of lewis structures.

The formula for nitryl chloride is CINO2 (in which N is the central atom). a.Draw the Lewis structure for the molecule, including all resonance structures. b.What is the N-O bond order? c.Describe the electron-pair and molecular geometries and give values for all bond angles. d.What is the most polar bond in the molecule? Is the molecule polar? e.The computer program used to calculate electrostatic potential surfaces gave the following charges on atoms in the molecule: A =-0.03, B = -0.26, and C = +0.56. Identify the atoms A, B, and C. Are these calculated charges in accord with your predictions?

2. This question uses sulfur trioxide and the sulfite ion and sulfur trioxide a. Draw both Lewis structures. b. Give the shape and geometry of each structure.

Why is this theory successful? Can you name some of the limitations of the theory? Drag the appropriate items to their respective bins. to determine the shape of the molecule or ion to determine the formulas of ionic compounds Lewis theory allows us to account for the paramagnetism of some species (e.g. oxygen) to determine how the bonds in the molecules and ions form to predict what molecules or ions will be stable, which will be more reactive, and which will not exist to account for the low melting points and boiling points of molecular compounds compared to ionic compounds Lewis theory does not allow us Reset Help
