- A compound has the molecular formula C6H12O2. Its IR spectrum shows a strong absorption band near 1740 cm-1. Its 1H NMR spectrum consists of two singlets at δ 1.2 and δ 3.6. Which is the most likely structure of the compound?arrow_forwardOn prolonged storage, the compound shown below reacts to give a product of molecular formula C12H:60. What is the structure of this product? ÇI OH • C:2H10arrow_forwardIndole smells terrible in high concentrations but has a pleasant floral-like odor when highly diluted. Its structure is The molecule is planar, and the nitrogen is a very weak base, with Kp = 2 × 10-12. Explain how this information indicates that the indole molecule is aromatic.arrow_forward
- A compound with formula C7H12O is treated with sodium borohydride in methanol to yield 2,2-dimethylcylopentanol. Write a reaction scheme showing the structures of the reactant, the reagents, and the product. Will the product be optically active? Explain.arrow_forwardWhich of the following compounds does NOT absorb in the UV-visible range (200 - 900 nm)? Select one: Phenol Hexane 1,4- Benzoquinone Pentan-1,4-dien-3-one[CH2=CHC(=O)CH=CH2] Benzenearrow_forward5. There are three constitutional isomers with the molecular formula, C6H12. When heated with chlorine (Cl₂) at 300C, ● Isomer A gives a mixture of four monochlorination products. Isomer B gives a mixture of three monochlorination products. Isomer B gives only one monochlorination product. From this information, deduce the structures of isomers A, B, and C. Draw the products upon chlorination of each to explain your answer on the back of this sheet..arrow_forward
- a) If the pH value of an aqueous solution of trimethylamine [(CH3)3N] is 10.75, what should be the molarity of this solution? (CH3)3N + H2O ↔ (CH3)3NH+ + OH-, Kb = 6,3 × 10-5 b) What will be the pH of the solution prepared by dissolving 8.35 g of aniline hydrochloride (C6H5NH3+Cl-) in 750 mL of 0.215 M aniline (C6H5NH2)? Is this solution an effective buffer? Explain (Kb = 7,4 × 10-10 for aniline, C: 12.0 g / mol, H: 1.0 g / mol, N: 14.0 g / mol, Cl: 35.4 g / mol) .arrow_forwarda) If the pH value of an aqueous solution of trimethylamine [(CH3) 3N] is 10.75, what should be the molarity of this solution?

- Two substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1. Identify the products.arrow_forwardDraw the structure of each product from the reaction of benzene with 2-chloro-1-methylcyclohexane using AlCl 3 as the catalyst and Identify the major product.arrow_forwardA chemist synthesized compound X as a racemic mixture. When the ketone group in X was enzymatically reduced to the corresponding alcohol, a 100% yield was obtained of the product shown below. Choose the statement that best describes this result. ОН enzyme C;H1 `OCH,CH; pH 4.0 C3H1 `OCH,CH3 ОН ÕH X (racemic) (100% yield) One enantiomer of compound X reacts quickly with the enzyme. The other enantiomer of compound X is unreactive, but rapidly equilibrates with the reactive enantiomer under the reaction conditions. Since compound X was racemic, it makes sense that only a single product was obtained. O The product is a meso compound, so either enantiomer of compound X gives the same product. One enantiomer of compound X reacts quickly with the enzyme, while the other enantiomer of compound X remains unchanged.arrow_forward
