- Nomenclature: provide the systematic names or structure of each of the following compounds. Include E/Z/R/S where relevant.12.Use of KMnO, to effect oxidative cleave of the alkene J, C3H16, yields two fragments, one of which is butanoic acid and the other a ketone, Q. When J reacts with one molar equivalent of H-Cl, the alkyl halide K, C3H17CI, is formed. What are the structures of J, J, and Q? Write all the reactions, and show your reasoning.The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.
- complete the synthetic schemeEthane reacts with chlorine (Cl2) in the presence of ultra-violet (UV) light, to produce 1-chloropropane (CH3CH2Cl) and hydrogen bromide (HCl). As shown in the equation below.CH3CH3+ Cl2→ CH3CH2Cl+ HClDescribe the reaction mechanism of the reaction between ethane and chlorine to produce 1-chloroethane. The description should be detailed and must include the type of bond fission that takes place. You may sketch and insert suitable diagrams to aid your description if you wish.Write the structure of the organic product in each of the following reactions. If electrophilic aromatic substitution occurs assume only monosubustitution.
- Only one of the chlorine atoms in the molecule, 3,4-dichloronitrobenzene, will undergo nucleophilic substitution. Indicate which position will react and provide the expected product for the given reaction using reaction intermediates (resonance structures).When 2-methylpropane is monochlorinated in the presence of light at room temperature, 36% of the product is 2-chloro-2-methylpropane and 64% is 1-chloro-2-methylpropane. From these data, calculate how much easier it is to remove a hydrogen atom from a tertiary carbon than from a primary carbon under these conditions.4. The following molecule was subjected to two different conditions. Provide the product in each case. 1. Mel, K₂CO3 2. Ag₂O, A mCPBA, Δ
