ORGANIC CHEMISTRY W/CONNECT & ALEKS
- Aspirin is prepared by the reaction of salicylic- acid with acetic anhydride as shown in the following equation. The stoichiometry of the reaction is given in the equation. Acetic acid is a by-product of the reaction and must be separated and removed so that aspirin can then be sold as a pure product. How many grams of aspirin can be prepared from 120 grams of salicylic acid? Assume that there is an excess of acetic anhydride. (Chapter 4) Acetylsalieylic acid (Aspirin)arrow_forwardWhich of the following gives the proper order for increasing solubility in water? * O Hexane < diethyl ether < butanol O Diethyl ether < hexane < butanol O Butanol < hexane < diethyl ether Diethyl ether < butanol < hexane O Hexane < butanol < diethyl ether octanoic acid is insoluble in water, soluble in NaOH and NaHCO3 O soluble in water and ether O insoluble in water and NaOH, soluble in HCl O insoluble in water, NaOH HCl and H2s04arrow_forwardCream of tartar is a white powder sometimes used in baking. (It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in the cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Allrecipies.com) Cream of tartar (KHC4H4O6) is the conjugate base salt of tartaric acid (shown to the right). The Ka for another similar acid is 8.7×10-3. What is the standard Gibb's free energy (in kJ/mol) for the dissociation of that other acid?arrow_forward
- 10 Regarding t-butanol and n-butanol, which is/ are correct statements of the following: |- Both are having equal solubility in water Il- t-butanol is more soluble in water than n- butanol III- Boiling point of t-butanol is lower than n-butanol IV- Boiling point of n-butanol is lower than t-butanol * Only I Only II Only II Il & II III & IVarrow_forwardb) Ph NaOH heat, dehydration (CH3)3CCHO KOH heat, dehydration NaOH heat,dehydrationarrow_forwardWhich is NOT a physical property of alcohols or phenols? O Phenols are generally only slightly soluble in water. O The hydroxyl group of an alcohol is nonpolar. The solubilities of normal primary alcohols in water decrease with increasing molecular weight. Boiling points of normal primary alcohols increase with increasing molecular weight.arrow_forward

Which of the functional groups in the top list must be on a terminalC in the carbon chain?arrow_forwardWhy is water more acidic than ethanol but slightly less acidic than methanol?arrow_forward9. An organic compound, P, has the molecular formula, C3H6O. It reacts with chromic acid to form Q. Q reacts with ethanol in the presence of concentrated sulphuric acid to give a sweet-smelling liquid, R. a) Identify P, Q and R. b) Arrange in decreasing order the boiling point of compound P, Q and ethanol. Explain. c) Compare acidity of Q and propanolarrow_forward
- 1. Answer Only True or False? Ketones can be oxidized by Tollen's reagent? True False Refer to the following mixtures: Mixture A: Liquid and solid mixture Mixture B. Liquid mixture whose boiling points are similar. Mixture C. Liquid mixture with high boiling point. Mixture D. Heat sensitive liquid mixture. Which of the following distillation can be applied for Mixture C? vacuum distillation fractional distillation simple distillation none of these In the experiment synthesis of acetyl salicylic acid, what is the purpose of adding water after salicylic acid and acetic anhydride reacted? the destroy the unreacted salicylic acid the destroy the unreacted acetic anhydride to increase the yield of the reaction to dilute the sulfuric acid ————— What smell/odor is expected for the complete reaction of benzyl alcohol and formic acid in the presence of catalytic amount of sulfuric acid? pineapple smell orange smell banana smell wintergreen smell finger nail polish smell…arrow_forwardexplain why methanethiol, CH3SH, has a lower boiling point (6°C) than methanol, CH3OH (65°C), even though methanethiol has a higher molecular weightarrow_forward3. Molecules with more than one alcohol group can react with thionyl chloride (SOCI.) in a way that is different from that of single alcohols. Consider the example below.
