(a) Do you expect this association to be stronger or weaker than that of compounds containing an O-H group? (b) Based on your answer to part (a), which would you predict to have the higher boiling point, 1-butanol or 1-butanamine?arrow_forward
- Suppose you were given the structural formula of compound B but only the molecular formulas for compound A and the starting bicyclic amine. Given this information, is it possible, working backward, to arrive at an unambiguous structural formula for compound A? for the bicyclic amine?arrow_forward(b) A compound with the molecular formula C4H9CI has four structural isomers. Write the structural formulas for all the four isomers. (c) Arrange the following compounds in order of increasing acidity, and explain the reasons forarrow_forwardGiven that C6H11COOH has a pKa = 4.8 and C6H11N+H3 has a pKa = 10.7, (a) What pH would you make the water layer to cause the carboxylic acid to dissolve in the water layer and the amine to dissolve in the ether layer? (b) What pH would you make the water layer to cause the carboxylic acid to dissolve in the ether layer and the amine to dissolve in the water layer?arrow_forward
- In an attempt to synthesize compound C through a two-step process, a chemist discovered after completing the first step that they had inadvertently produced two distinct compounds, A and B. Upon examining the infrared spectroscopy (IR) results, it was observed that both A and B exhibited peaks indicative of a ketone and an ester group. Please provide the molecular structures of A and B. OEt NaOEt ΕΙΟ A B In a chemical experiment, they noticed that both components, A and B, from a combined sample turned into a new compound, C, during the following stage. The task is to determine what compound C looks like and explain how compound A or B changes into compound C through a reaction. Compound C should be the primary molecule containing carbon created in this process, not just a by-product. A B H3O+, H₂O, A Mechanism = сarrow_forward11.27: Tell which is the stronger base and why? Aniline or p-cyanoaniline b) aniline or diphenylamine WH₂ |ال 11.30: Place the following substances, which have nearly identical formula weights, in order of increasing boiling point? 1-aminobutane, 1-butanol, methyl propyl ether, pentanearrow_forwardWrite the chemical equation for the acid dissociation of acetaminophen, C8H9O2N. Write the Ka expression for the acid dissociation of acetaminophen.arrow_forward

(c) The drug isotretinoin is formed by reaction of X and Y. What is the structure of isotretinoin? Although isotretinoin (trade name Accutane or Roaccutane) is used for the treatment of severe acne, it is dispensed under strict controls because it also causes birth defects. PPha NaOCH,CH3 HO- isotretinoin HO A Br X Yarrow_forwardGive the chemical tests to distinguish between following pair of compounds : (i) Propanol and propanone (ii) Ethyl acetate and methyl acetate (iii) Benzaldehyde and benzoic acid (iv) Benzaldehyde and acetaldehyde (v) Formic acid and acetic acid (vi) Propanal and propanol (vii) Ethanoic acid and ethylethanoatearrow_forwardUsing the data in Appendix C, determine which of the following bases is strong enough to deprotonate acetonitrile (CH3CN), so that equilibrium favors the products: (a) NaH; (b) Na2CO3; (c) NaOH; (d) NaNH2; (e) NaHCO3.arrow_forward
