1.	SN^2 reactions of alkyl halides is a bimolecular reaction which take place through formation of a transition state. The rate of reaction depends on the concentration of alkyl halide andnucleophile.The reaction is favoured by strong nucleophlie in polar aprotic solvents.Which of the following undero substitution by SN^2 mechanism at a faster rate from other
Answer» `CH_3CH_2CH_2Br`<BR>`CH_2 = CH - CH_2 - Br` `CH -= C - CH_2Br` all the above SOLUTION :`CH -= C - CH_2 - Br to ` SP (more E.N) , `E.N propE.W.G prop SN^2`
