Concept introduction:
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
E1 and E2 are the two types of elimination reaction.
Nucleophilic substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any nucleophile is called nucleophilic substitution reaction.
A nucleophile is a molecule or atom with most negative charge.
There are two types of nucleophilic substitution reactions:

- Give the product or products that you would expect from the following reaction. In each case give the mechanism as SN1, SN2, E1, E2 and predict the relative amount of each product. - (CH3)3CCl+OH- / CH3OH -->arrow_forward2. The following reaction results in two possible carbocation rearrangement products, each of which can be characterized by a change in the ring size. Give structures for both products. There is no need to show the mechanism of the reaction. HCI (conc)arrow_forwards) When the following compound undergoes SN1 solvolysis in ethanol (why, if it is not tertiary in structure? Hint: think of ways that stabilize a carbocation except it being tertiary), three products are obtained. Propose a mechanism to account for the formation of these products and make a prediction which product(s) is/are major/minor. CH₂Br CH3CH₂OH A + Солено OCH₂CH3 + OCH₂CH3arrow_forward
- Write down all possible alkene products from the following Elemination reaction (no mechanism is required) indicate which one will be major product. And explain it?arrow_forwardМЕСНANISMS 1,2-epoxy-1-methylcyclopentane undergoes both acid-catalyzed and base-catalyzed opening of the epoxide ring to form two different products. > Using ethanol as the solvent and an appropriate acid, show the steps in the acid catalyzed mechanism, writing structures for all products of the steps. Circle the major product(s). > Using ethanol as the solvent and an appropriate base, show the steps in the base- catalyzed mechanism, writing structures for all products of the steps. Circle the major product(s). 1,2-epoxy-1-methylcyclopentane CH3arrow_forward(b) Consider the reaction of 1-bromobutane with a large excess of ammonia (NH3). Draw the reactants, the transition state, andthe products. Note that the initial product is the salt of an amine (RNH3+ Br - ), which is deprotonated by the excess ammonia to give the amine.arrow_forward
- Consider the attached SN2 reaction. Question: What happens to the reaction rate in each of the following instances? [1] The leaving group is changed from Br− to I−; [2] The solvent is changed from acetone to CH3CH2OH; [3] The alkyl halide is changed from CH3(CH2)4Br to CH3CH2CH2CH(Br)CH3; [4] The concentration of −CN is increased by a factor of five; and [5] The concentrations of both the alkyl halide and −CN are increased by a factor of fivearrow_forwardI cannot figure out this question about ozonolysis of an alkene? There are two double carbon bonds to choose from on the ring, so how do we know what is being acted on? (if that makes sense) Thank you!arrow_forwardWhich reaction(s) would you use to convert Cyclohexanone to Methylenecyclohexane (A) and 1-Methylcyclohexane (B)? Hint: The single step process A gives product A exclusively in high yield. The two-step process B gives the B as the major product. Answer must be in this format: In the first text box, write A) name of the one step reaction. In the second text box, write B) name of the reagent or reaction for the first step: name of the reagent or reaction for the second step. CHarrow_forward
- The 3° alcohol shown in the following equation forms the same carbocation with either acid, but forms different final products depending on the acid used. This is because (a) sulfuric is a much stronger acid that HBr, (b) water is given off as product is formed, (c) Br is a better nucleophile than HSO4" , (d) HBr has only 1 acidic proton. + H,SO4 + HSO4 но, HBr + Br Brarrow_forwardWrite whether it will be E1, E2, SN1, and/or SN2 Show the mechanism(s) Write the MAJOR product(s) State the stereochemistry of the product(s), when applicablearrow_forwardConsider the following reaction. + PhLi (2 eq.) then water a) Propose a structure for the final product. b) Give a complete mechanism for the transformation. c) Draw an energy diagram of the transformation and briefly comment on the relative energies of the starting material, final product, and any intermediate(s), and about the rate determining step.arrow_forward
