Chemical Principles: The Quest for Insight
- Predict whether the bonds in the following compounds are ionic or covalent: (a) NaI (sodium iodide); (b) H 2O 2 (hydrogen peroxide).arrow_forwardWrite the electron configuration for each of the following ions and determine which one possess noble-gas configurations: (a) Sr2+; (b) Ti2+; (c) Se2-; (d) Ni2+; (e) Br-; (f) Mn3+.arrow_forwardTestosterone is an anabolic steroid. The structure of testosterone is shown below. What is the geometry of the electron pairs at (iii) ? Hint: atom (iv) has been completed for you as an example. (iv) bond angle: 109.5°, geometry of the electron pairs: tetrahedral, shape of the bonds: tetrahedral i iii •··||||I H ····||||I ii ivarrow_forward
- Draw a Lewis electron-dot symbol for (a) Sr; (b) P; (c) S.arrow_forwardDefine the following phenomena with reference to main group compounds: (d) multicenter electron deficient bondingarrow_forwardFor many years after they were discovered, it was believed that the noble gases could not form compounds. Now we know that belief to be incorrect. A mixture of xenon and fluorine gases, confined in a quartz bulb and placed on a windowsill, is found to slowly produce a white solid. Analysis of the compound indicates that it contains 77.55% Xe and 22.45% F by mass.(a) What is the formula of the compound?(b) Write a Lewis structure for the compound.(c) Predict the shape of the molecules of the compound.(d) What hybridization is consistent with the shape you predicted?arrow_forward
- (a) Why do stable xenon fluorides have an even number of F atoms? (b) Why do the ionic species XeF₃⁺ and XeF₇⁻ have odd numbers of F atoms? (c) Predict the shape of XeF₃⁺ .arrow_forwardChemical species are said to be isoelectronic if they have the same Lewis structure (regardless of charge). Consider these ions and write a Lewis structure for a neutral molecule that is isoelectronic with them. (a) CN–, (b) NH4+ (c) CO3 2–arrow_forwardDraw a Lewis electron-dot symbol for (a) Ba; (b) Kr; (c) Br.arrow_forward
- Write condensed electron configurations for the following: (a) Zr; (b) V3+; (c) Mo3+.arrow_forwardTestosterone is an anabolic steroid. The structure of testosterone is shown below. What is the shape of the bonds at (i) ? Hint: atom (iv) has been completed for you as an example. (iv) bond angle: 109.5°, geometry of the electron pairs: tetrahedral, shape of the bonds: tetrahedral iii ·····|||I H **…||||I H ii ivarrow_forward(c) Draw the orbital diagrams and Lewis symbols to depict the formation of Na* and CI ions from the atoms. Give the formula of the compound formed. (d) The predicted bond length for HF is 109 pm (the sum of the covalent radii of H, 37 pm and F. 72 pm), however the actual bond length for HF is shorter (92 pm). It was observed that the difference between predicted and actual bond lengths becomes smalleor going down the halogen group from HF to HI Describe these observationsarrow_forward
