Benzyne - organic chemistry

(1) 1, 2-Didehydrobenzene, C₆H₆ and its derivatives are known as benzyne or arynes and the simplest member is benzyne.
    
(2) It is neutral reaction substance made from benzene ring from removing two substituents, of ortho positions, one in the form of electrophile and other in the type of nucleophile leaving behind two electrons to be distributed among two orbitals.
   
(3) Benzyne substances is aromatic in behavior.
   
(4) While halobenzene is heated along with sodamide creation of benzyne occurs.     

(5) (i) It works as dienophile and provides Diels-Alder reaction with diene.
