Explain based on the HSAB concept (“hard and soft acids and bases”) why NaCl is very...
Draw the two Lewis structures for the thiocyanate anion [SCN]-. Using the HSAB (hard soft acids and bases) concept, predict the binding mode of the [SCN]- ligand in complexes with the metal ions Hg2+ and Zn2+.
Using the 'hard'/'soft' classification of acids and bases, determine whether Keq > 1 or keq < 1 for the following reaction. Briefly explain. Cl3Al-PEt3 + Clzin-NMe3 = Cl3Al-NMe3 + Cl3In-PEt3 For parts (a) and (b), state which of the two solutions has the lower pH: (a) 0.1 M K(NO2)(aq) or 0.1 M K(NO3)(aq) (b) 0.1 M FeCl3(aq) or 0.1 M (FeCl4] (aq)
Ligands and hard-soft acids and bases inorganic chemistry Is a square planar and has D4h symmetry. In D4h symmetry, what is the reducible of each LGO listed below (LGO1 and LGO2) (the reducible representation for each L GO. That should have asked for the character term corresponding to each symmetry operation for the LGO (LGO1 and LGO2)? (Hint: In other words, if the LGO is symmetric with respect to the operation listed, it should be given a value of 1....
Which of the following is a true statement about the Lewis definition of acids and bases? Select the correct answer below: The Lewis definition of acids and bases is based on donating or accepting an electron pair. O The Lewis definition of acids and bases is based on the production of HO or OH ions in water solutions O The Lewis definition of acids and bases is based on donating or accepting a proton. O none of the above MORE...
inorganic chemistry Explain the following: i) (a) Reaction of ammonia with iodomethane is not a very practical way to prepare methylamine. ii) Ketones are less reactive towards nucleophiles than aldehydes. ii) Reaction of propanone with CH3MgBr in water does not produce an alcohol. iv) 3-Hydroxypropanoic acid is less acidic than 2-fluoropropanoic acid. (12) (b) i) Classify CCl4, BrFs, HF and C&Hs as protic or aprotic solvents and write equations for the autoionisation of those that autoionise. ii) Describe the Hard...
An Acid-Base Titration Lab Define Lewis acids and bases. Give an example of each. Based on the Brønsted-Lowry theory of acids and bases, complete the equations for the following acid-base reactions. In your answer be sure to indicate each conjugate acid-base pair: HNO3 + OH- à CH3NH2 + H2O à OH- + HPO4-2 à When discussing the theories of acids and bases, the Arrhenius, Brønsted-Lowry, and Lewis theories will each describe compounds in their own unique and different way. Based...
Why should a vegetarian be concerned about "limiting" amino acids? Briefly explain why this concept is a concern in the vegetarian diet and how a vegetarian can compensate for limiting amino acids in specific foods.
1) Brief answers a) Explain why FeS is much less solute in water than Fe(OH)2 and Fe(OH)2 is much more soluble than Fe(OH)3 b)will Cr3+react more strongly with Cl-or PR3. Why? 2) Brief answers a) Would you expect lead (Pb2+ soft to be found oxide in nature? b) Explain the following observation interns pf the HSAB theory: OH- + CH3HgS --> CH3HgOH +S2- Equilibrium displaced to the left.
The Nature of Acids and Bases: Exploring the pH Scale PRE-LAB QUESTIONS 1. Where do water and hydrochloric acid (HCI) lie on the pH scale in relation to each other? Water is a neutral molecule at STP it has equal concentrations of hydronium ions [H3O+] 2. Give an example of a buffer and describe what it is used for 3. Explain why conjugate pairs must be composed of weak acids and bases. I
