Basic Organic Chemistry(Quiz-3) 1 / 5 Which of the following is the known name for the reaction given below?(where, X=Cl, Br, I, OTf; R2=Alkyl, aryl, H; R3=alkyl, aryl) Ullmann reaction Gabriel phthalimide synthesis Buchwald-Hartwig Reaction Chan-Lam coupling The Buchwald–Hartwig amination is a chemical reaction used in organic chemistry for the synthesis of carbon–nitrogen bonds via the palladium-catalyzed cross-coupling of amines with aryl halides. 2 / 5 Which of the following organic compound with molecular formula C3H C12 exhibits only one signal in the IH NMR spectrum? 1, 2-dichloropropane 1, 1-dichloropropane 2, 2-dichloropropane 1, 3-dichloropropane Only (a) compound has all chemically equivalent hydrogen. So, give only one peak. 3 / 5 An organic compound (MF; C8H10O) exhibited the following 1H NMR special data: 62.5 (3H, s), 3.8 (314, s), 6.8 (2H, d, J 8 Hz), 7.2 (2H, d, J 8 Hz) ppm. Which of the following is that compound among the choices? 4-methylbenzyl alcohol 4-methyl anisole 4-ethylphenol 2-ethylphenol C8H10O3Ha –> 3.8, singlet (deshielded because of –I of oxygen)3Hb –> 2.5, singlet (No such –I)2Hc –> 7.2, doublet (deshielded because of anisotropy effect of benzene as well as because of –I of oxygen)2Hd –> 6.8, doublet (deshielded because of anisotropy of benzene). 4 / 5 Which of the following complex is in which organic ligand is having only bond with metal? (η5-C5H5)2Fe (η5-C6H6)2Ru W(CH3)6 K[PtCl3(C2H4)] CH3 is the only σ-donor ligand while C2H4, C5H5, C6H6 are π-acceptor ligands. 5 / 5 Which of the following is the major organic product obtained from the following reaction? 3,5-dimethyl-3-heptanol 3,5-dimethyl-4-heptanol 4,7-dimethyl-4-heptanol 2,4-dimethyl-4-heptanol It is also important that products are identified accurately using IUPAC nomenclature: 4,7-Dimethyl-4-heptanol is not an IUPAC name.
