Treatment of cyclopentene with peroxybenzoic acid ________.    

Which of the following structures are correct resonance structures of the following organic molecule?      A                                                      B                                                            C                                                                    D            

Which of the following statements about carbon is NOT correct?    

What will be the chief product from the following reaction sequence?   D

How many secondary (2°) carbons are found in 5-ethyl-3,3,4-trimethylheptane?  

The acid-catalyzed Markovnikov addition of H2O to 1-butene produces a ____________ as the major product?  

What is the major organic product of the following reaction?           

The reaction of benzyl bromide (C6H5CH2Br) with azide ion (N3-) is shown below.  When the benzyl bromide concentration is doubled and azide concentration is held constant, the reaction rate is observed to increase by a factor of two.  When the azide concentration is doubled and the benzyl bromide concentration is held constant, the rate of the reaction doubles.  What is the correct rate law for this reaction?                                                C6H5CH2Br  +  N3- ——>  C6H5CH2N3  +  Br- I.   Rate = k [C6H5CH2Br ]2 [N3- ]2 II.  Rate = k [C6H5CH2Br ]2 [N3- ] III. Rate = k [C6H5CH2Br ]4 [N3- ]2 IV. Rate = k [C6H5CH2Br ] [N3- ]
