Concept introduction:
Nucleophilic substitution reaction is a reaction in which one nucleophile (weak nucleophile) is replaced by a strong nucleophile.
A nucleophile is a molecule or atom with the highest negative charge.
There are two types of nucleophilic substitution reactions:

- Hw.198.arrow_forwardAlkenyl halides such as vinyl bromide, CH2=CHBr, undergo neither SN1 nor SN2 reactions. What factors account for this lack of reactivity?arrow_forwardAn ion with a positively charged nitrogen atom in a three-membered ring is called an aziridinium ion. The following aziridinium ion reacts with sodiummethoxide to form compounds A and B: If a small amount of aqueous Br2 is added to A, the reddish color of Br2 persists, but the color disappears when Br2 is added to B. When the aziridinium ion reacts with methanol, only A is formed. Identify A and B.arrow_forward

Explain why butene oxide is much more reactive than its isomer, tetrahydrofuran, which is also a cyclic ether: H₂C-CH₂ H₂C CH₂ tetrahydrofuran Illustrate how butene oxide reacts with ammonia, showing details of the mechanism leading to the final product, C4H11 NO.arrow_forward(a) Give the names of reagents and conditions for each of the reactions I and IIarrow_forward
- Under certain reaction conditions, 2,3-dibromobutane reacts with two equivalents of base to give three products, each of which contains two new p bonds. Product A has two sp hybridized carbon atoms, product B has one sp hybridized carbon atom, and product C has none. What are the structures of A, B, and C?arrow_forwardCompound A has the formula C₂H₁9Cl. B is a C₂H19Br compound. A and B undergo base-promoted E2 elimination to give the same alkene C as the major product as well as different minor products. C reacts with one molar equivalent of hydrogen in the presence of a palladium catalyst to form 2,6-dimethylheptane. Addition of HCI to C yields A as the major product. Propose structures for A and B. • Do not use stereobonds in your answer. • In cases where there is more than one possible structure for each molecule, just give one for each. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. ● ▾ *%-85 ChemDoodle Qt Jn [F 116arrow_forwardList the following alkyl halides in order of decreasing reactivity toward SN1/E1 reactions (from 1: most reactive to 4: least reactive).arrow_forward
