1.	(i) Give reaction for bromination of ethane. (ii) Is this reaction suitable for pure bromoethane ? Why ? (iii) Give tha name of mechanism of reaction and name of stages occurred in reaction. (iv) Give reaction for first stage. (v) Which type of bond cleavage occurred in first stage ?
Answer» Solution :(i) `C_(2)H_(6) + Br_(2) overset(hv)RARR C_(2)H_(5)Br + HBR` (ii) This reaction is not suitable for the preparation of pure bromoethane because by this reaction mixture of BROMOALKANE is obtained and their separation is too difficult. (iii) In free radical substitution reaction the various STAGE is initiation, propagation and termination. (iv) `Br_(2)rarr 2Br` (v) Homolysis of bond
