- As a general rule, MX molecules (where M represents a central atom and X represents terminal atoms; n = 2 5) are polar if there is one or more lone pairs of electrons on M. NH3 (M = N, X = H, n = 3) is an example. There are two molecular structures with lone pairs that are exceptions to this rule. What are they?arrow_forwardThe 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?arrow_forwardPredict the molecular structure (including bond angles) for each of the following. (See Exercises 115 and 116.) a. ICl5 b. XeCl4 c. SeCl6arrow_forward

Explain.arrow_forward4.Examine the model and real structures for SO2. A.In what way does the central atom violate the octet rule? When is it possible for molecules to have this exception to the octet rule? B.Calculate the difference in the bond angle between the real and model structure? Is this difference larger or smaller than the difference observed for H2O? Why is the deviation between the real and model structure different for SO2compared to H2O? The deviation for H2O is 5 degreesarrow_forwardDraw the Lewis Structure of XeF4 Molecular Geometry? Ideal Bond Angles?
