Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

True or false? 2-bromo-2-methylpropane undergoes SN1 rather than SN2 because the nucleophile experiences steric hindrance, and a stable carbocation can be formed. When hydroxide ion reacts with 1-chloropropane the main product is 1-propanol.
Rearrangements can occur during the dehydration of 1° alcohols even though no 1° carbocation is formed—that is, a 1,2-shift occurs as the C— OH2+ bond is broken, forming a more stable 2° or 3° carbocation, as shown in Equation [1]. Using this information, draw a stepwise mechanism for the reaction shown in Equation [2]. We will see another example of this type of rearrangement in Section 16.5C.
1. Which of the following is the strongest nucleophile? Refer to the diagram below with an MeOH, MeSH, etc. 2. Which of the following is true about the stereochemistry of SN1 reaction?a.retention of configuration at the electrophilic centerb.50:50 mixture of retention and inversion of configuration at the electrophilic centerc.inversion of configuration at the electrophilic centerd. slightly more inversion than retention at the electrophilic center
Benzene is one of the compounds used as octane enhancers in unleaded gasoline. It is manufactured by thecatalytic conversion of acetylene to benzene: 3C2 H2(g) ⇌ C6 H6(g). Which value of Kc would make this reactionmost useful commercially? Kc ≈ 0.01, Kc ≈ 1, or Kc ≈ 10. Explain your answer
(True/False) The use of sodium iodide in acetone promotes SN2 mechanism for alkyl halide resulting in the formation of insoluble salts in the mixture. (True/false) For alkyl halides, we use a solution of AgNO3 in ethanol because ethanol is a polar protic solvent suited for SN1 mechanism. (True/False) 1-bromobutane, 2-bromobutane (aka sec-butyl bromide), tert-butyl bromide, benzyl chloride, and bromobenzene will not form precipitates in either 1M NaI/acetone and 2% AgNO3/EtOH.
Assume that 2-chloropropane reacts with CN− in an SN2 reaction. Use the JSME editor () to draw the structure of the substitution product of the reaction. The guide on how to draw your structure can be found here Important Note: When drawing the structures in the JME editor please adhere to the following formats: 1. If the nucleophile is OH−, DO NOT manually add the "H" to the final product 2. If the nucleophile is CN−, be sure to include the appropriate bonding between the C and N in the final product
1. What type of reaction is occuring in step 3? (halogenation, hydrohalogenation, reduction, keto–enol tautomerism, dehydrohalogenation, acid-catalyzed hydration, base-catalyzed hydration) 2. Which reagent is necessary for step 3? (Br2, HBr, H2/Pt, NaNH2, H20/H2SO4/HgSO4)
Monensin (1) is a potent antibiotic. JACS 1980, 102, 2118-2120. 1. Use arrows provided a pathway from (1) to (2) when we add a mild base sodium bicarbonate followed by iodine (I2). 2. What was a similar reaction between Br2 and an alkene? What did we name the intermediate?
Which of the following statements is TRUE regarding the reaction below? Options: The IR spectrum of the major organic product will show a broad absorption between 3000-3500 cm-1. The mass spectrum of the major organic product will show an M+2 peak in the molecular ion region. The reaction should proceed without carbocation rearrangement. The alkene is the electrophile and water is the nucleophile in the first step. HSO4- is the dominant nucleophile in the second step.
Show stereo chemistry and possible outcomes and the steps for the reaction.
Adjust the structures below to show the resulting intermediates.
Q4 Which statement below about Sn1 reactions is incorrect? (A) SN1 reactions are stepwise and have intermediates. (B) The slow step in a SN1 reaction is formation of the carbocation intermediate. (C) SN1 reactions have first order kinetics which means only the alkyl halide is involved in the rate limiting step. (D) The products of a SN1 reaction will be a pair of enantiomers. (E) An aprotic solvent is best for Sn1 reactions as they tend to help stabilize carbocation intermediates.
