Use the following three structures to answer questions 10-12 The relationship between I and III is: The same compound Enantiomers Diastereomers Constitutional isomers none of the above The relationship between I and II is: The same compound Enantiomers Diastereomers Constitutional isomers none of the above which of the above structures is (are) meso compounds? I II III II and III I and II none of the above In following reaction, experimentally one finds that if the concentration of PhCH2CH2OH is tripled, then the rate is triple. One also finds that if the concentration of HBr is doubled, the rate of reaction is doubled. Which of the following correctly describes the kinetics of the reaction? The reaction is third order in PhCH2CH2OH. The reaction is first order in HBr. The reaction is second order overall. The reaction is first order overall. None of the above. All of the above.
Explanation / Answer
10)they are the same compound
11)they are diastereomers
12)1 and III are meso compound
14)since on tripling the concentration of the organic compound, the rate triples. and on doubling the inorganic compound the rate double to the rate is propotional to the organic as well as the inorganic compount.
hence the reaction is an overall second order reaction
