              (C)                   Cl      & HCHO           (d) n-chloro hexane & Acetaldehyde


                                       CH3


 


 


Answers are given to be (a) and (b).


 


Ans) I have given a try from the options.


 


With (a), the first step made to eliminate Hydrogen Chloride and add Ph3P with a double bond.


                                                                    


                                                      Cl + Ph3P                                                   PPh3


-HCl


 


                 Now, with butane lithium, I made to add Li+ ion to phosphorus. Then, I have stopped working out and it made me confuse.


 


Now with (b), the same position had also arrived at BuLi. I was able to discriminate that the options (c) and (d) do not undergo the reaction.


 


Please reply me.
