Select one: True or False 1- In case of homo-binuclear covalent bond (of atoms of the same element) and hetero-binuclear covalent bond of very low electronegativity difference (as that between carbon and hydrogen), the bond is very strong and of no or minimum polarity hence not cleaves in water 2-In this compound complexation ( in the image ) is used for qualitative/quantitative identification of phenolic compounds where salicylic acid is chelated by the iron metal in ferric chloride to form water soluble violet color complex 3-Complexes are of different stability some are stable only in aqueous other are stable in both solid and solution however, for the maximum complex stability high metal anaionic charge, small transient metal atom radius and occupied d orbital are required.
Which of the following statements is INCORRECT concerning the two acids below? Options: Acetic acid has higher water solubility than benzoic acid. Acetic acid has a higher melting point than benzoic acid. Benzoic acid has a larger conjugated system. Benzoic acid is the stronger acid. Acetic acid has an electron donating group in it's structure.
A)Identify functional groups in the molecule B) Will the molecule be deprotonated, neutral of protonated at physiological pH? C) If treated with strong aqueous acid, what might happen to the molecule?
The global consumption of synthetic dyes is increasing due to increase in demand invarious processing/manufacturing industries. Analyze why among the large number of organic molecules, only relatively few moleculesare considered as dyes. Select any one dye which is used in industry and give justificationof type of the dye, its application in the industry and related reactions.
Write an equation to show the proton transfer between each alkene or cycloalkene and HCl. Where two carbocations are possible, show each.
Experimental observations show that thiocyanate (SCN- ), the conjugate base of thiocyanic acid (pKa = 1.1 at 25 °C), is quite soluble in neutral water at pH > 2. In the space provided below, explain this experimental observation. That is, why does SCN– readily dissolve in water when the pH > 2?
Recall from Section 1.10B that there is restricted rotation around carboncarbon double bonds. Maleic acid and fumaric acid are two isomers with vastly different physical properties and pKa values for loss of both protons. Explain why each of these differences occurs.
Which of the following distinguished scientists is correctly identified? There may be more than one correct answer. Adolf von Baeyer proposed the importance of ring strain Louis Vuitton separated crystals of tartaric acid and hence isolated enantiomers of tartaric acid Vladimir Prelog worked with Robert S. Cahn and Sir Christopher Ingold to establish the Cahn-Ingold-Prelog priority system for nomenclature Emil Fischer invented the Fischer projection to facilitate the depiction of stereochemical relationships.

Unknown Results - Solubility Test: - Slightly soluble Ceric Ammounium Nitrate Test: - Positive Iron (III) Chloride Test: - Negative Chromic Acid Test: - Positive Iodoform Test: - Negative Luca's Test: - Negative The known alcohols tested in this experiment are: Ethanol 1-Propanol 2-Propanol 1-Butanol 2-Pentanol 2-Methyl-2-propanol 1-Octanol Phenol Although you didn't carry out every test on all eight alcohols, you should be able to predict the results for the tests on the alcohols that you did not test. If your unknown alcohol is one of these eight known alcohols, which do you think yours is? Can you definitely identify it? Explain your answer using your test results and predicted results.
You came across an article debating the use of Prevacid® vs. Nexium®. While both drugs have the same therapeutic effect, one is sold as a racemate and the other is sold as a single enantiomer. Previous medications such as Thalidomide and Advair® have sparked a debate about the safety of drugs sold as a racemate. Why are drugs sometimes sold as a racemate?
What is going on from compound B to compound C? Can you please select all the options that apply
