 Which of the following species can react as a nucleophile to react in an SN1-type reaction?  (1) (CH3)2C=O (2) H2O (3) CN- (4) CH3Cl 

If the substrate, CH3CHBrCH2CH3, is replaced by CH3CHFCH2CH3 in a nucleophilic substitution reaction, then (1) the rate at which each reaction takes place is the same. (2) the reaction will take place at a much faster rate. (3) the rate of the reaction will be twice as fast. (4) the reaction will not take place. 

7. Which of the following nucleophilic substitution reactions will TAKE PLACE THE FASTEST?  (1)  CH2BrOHH2OCH2OH+    Br (2) OHH2O+    BrBrCH3CH3HO (3) OHH2O+    BrBrHHHO (4)  OHH2O+    BrCH3CH2BrCH3CH2OH 

 Which of the following species will react the fastest with CH3CH2CH2-I in a nucleophilic substitution reaction? (1)  (CH3)3CO (2) HO (3) H2O (4) CH3CO2
