NH₂ O₂N NaNO₂ aqueous HCI at 0°What is the major product fromed from the reaction below?Cyclohexene plus 1) Hg(OAc)2, H2O; 2) NaBH4; yields __________. HO2CCH2CH2CH2CH2CO2H a cyclic diketone cyclohexyne cyclohexanol OHCCH2CH2CH2CH2CHO
- The following product can be synthesized from the reaction of an alkene with Hg(OAc)2 followed by reduction with NaBH4. Draw all possible alkenes that will give the product shownDraw all of the substitution and elimination products formed from the given alkyl halide with each reagent: (a) CH3OH; (b) KOH. Indicate the stereochemistry around the stereogenic centers present in the products, as well as the mechanism by which each product is formed.N(CH2CH3)3 + HNO3 --------> a.) rewrite the reaction using bond-line structure of reagents and products of the reaction b.) supply the curved arrows explaining the mechanism of the reaction
- Alkyl halides undergo elimination reactions with Brønsted–Lowrybases. The elements of HX are lost and an alkene is formed. Explain this ?2H2S(g) + SO2(g) <--> 3S(s) + 2H2O(g) Would this reaction be favored at a high or low temperature?Melamine, used as a fire retardant and a component of the writing surface of white boards, can be prepared from s-trichlorotriazine through a series of SNAr reactions with ammonia. The first substitution takes place rapidly at room temperature. The second substitution takes place near 100 °C, and the third substitution requires even higher temperature and pressure. Provide an explanation fatr this reactivity.
