Consider the Lewis structure shown below. (a) Does the Lewis structure depict a neutral molecule or anion? If it is an ion, what is the charge on the ion? (b) What hybridizationis exhibited by each of the carbon atoms? (c) Arethere multiple equivalent resonance structures for the species?(d) How many electrons are in the π system of the species?
s it possible to draw a resonance structure with the lone pair? What is the hybridization of the heteroatom? Draw a valence bond orbital diagram to show the location of the lone pair (you do not need to draw any orbitals to show s bonds). In what orbital are the electron pairs located?
Consider the following flat drawing of methane (CH4) . a. What is HCH bond angle implied by this drawing if you assume it is flat? b. Are the electron domains of this flat CH4 spread out as much as possible? c. Use model materials to make a model of CH4 (methane). If you assembled it correctly, thefour bonds (bonding electron domains) of your model will be 109.5° apart. d. In which representation, the drawing above or the model in your hand (circle one) are theH’s of CH4 more spread out around the central carbon? e. Confirm that your model looks like the following drawing. The wedgebond represents a bond coming out of the page, and the dash bondrepresents a bond going into the page f. You will often see methane drawn as if it were flat (like on the previous page). Why is thismisleading, and what is left to the viewer’s imagination when looking at such a drawing?
The antibiotic thiarubin-A was discovered by studying the feeding habits of wild chimpanzees in Tanzania. The structure for thiarubin-A is a. Complete the Lewis structure, showing all lone pairs of electrons. b. Indicate the hybrid orbitals used by the carbon and sulfur atoms in thiarubin-A. c. How many and bonds are present in this molecule?
How many and bonds are present in the molecule HCN?
Draw the Lewis electron dot structures for these molecules, including resonance structures where appropriate: (a) CS32 (b) CS2 (c) CS (d) predict the molecular shapes for CS32 and CS2 and explain how you arrived at your predictions
Use VSEPR to explain why the HBH bond angle of BH3 is 120°. (Hint: What is one-third of360°?)
For each of the following molecules, complete the Lewis structure and use the VSEPR model to determine the bond angles around each central atom. Note that the drawings are only skeleton structures and may depict the angles incorrectly.
7.57 What observation about molecules compels us to consider the hybridization of atomic orbitals?
(a) Predict the geometry of the SbCl52 ion, using the VSEPR method. (b) The ion SbCl63 is prepared from SbCl52 by treatment with Cl . Determine the steric number of the central antimony atom in this ion, and discuss the extension of the VSEPR theory that would be needed for the prediction of its molecular geometry.
Ozone (O3) has a nonzero dipole moment. In the molecule of O3 , one of the oxygen atoms is directly bonded to the other two, which are not bonded to each other. (a) Based on this information, state which of the following structures are possible for the ozone molecule: symmetric linear, nonsymmetric linear (for example, different OO bond lengths), and bent. (Note: Even an OO bond can have a bond dipole if the two oxygen atoms are bonded to different atoms or if only one of the oxygen atoms is bonded to a third atom.) (b) Use the VSEPR theory to predict which of the structures of part (a) is observed.
How many ?σ and ?π bonds are in this molecule?
