Concept explainers
(a)
Interpretation:
The reason for not forming pentafluoride by nitrogen should be suggested.
Concept introduction:
In the group-15, the valence shell configuration of all elements is
(b)
Interpretation:
The structure of
Concept introduction:
VSEPR is the theory purposed to explain the geometry of those molecules mainly which have lone pairs on the central atom as due to presence of lone pair and bond pairs, the repulsion plays important role in the determination of molecular geometry of the molecule.

- Which member of the following pairs would you expect to be more energetically stable? Justify each choice. a. NaBr or NaBr2 b. ClO4 or ClO4 c. SO4 or XeO4 d. OF4 or SeF4arrow_forwardDescribe the type of bonding that exists in die F2(g) molecule. How does this type of bonding differ from that found in the HF(g) molecule? How is it similar?arrow_forwardOxygen forms double bonds in O2, but sulfur forms single bonds in S8. Why?arrow_forward
- Silicon is in the same group of the periodic table as carbon and,like carbon, can form up to four single bonds. Many science fiction stories have been based on the premise of silicon-based life. Is this realistic? What characteristics of silicon make it less well adapted than carbon as the central organizing element for life? To answer this question, consider what you have learned about carbon’s bonding versatility, and refer to a beginning inorganic chemistry textbook for silicon’s bonding propertiesarrow_forward9. Provide the electron configuration for the B2, C22, and N₂ ions. What are their magnetic properties?arrow_forward28. Estimate the enthalpy (change in energy) of reaction for 2 SO(g) + O2(g) →2 SO2(g) using bond energies. Assume that sulfur in SO2 (g) has an expanded octet. -> Bond Energy (kJ/mol) 498 265 a. 498 kJ/mol c. -498 kJ/mol bь. 731 kJ/mol d. -32KJ/molarrow_forward
- When determining if a bond is polar, we must evaluate the difference in electronegativity (ΔEN) of the atoms involved in the bonding. 1. What is ΔEN for germanium and nitrogen? 2. What is ΔEN for silicon and tellurium?arrow_forwardWhy is SnCl4 not classified as a salt?arrow_forwardWhat is the molecular structure of each of the following molecules? You may wish to review the chapter on chemical bonding and molecular geometry. (a) XeF2. (b) XeF4. (c) XeO3. (d) XeO4. (e) XeOF4arrow_forward
