guys.... y do u all think i posted this.... [3]
it is not the second one....
i really liked the question....
it has been given in the daily test series of vidyadrishti.com [12/03/09]...
think about mechanism...
1the first one is more reactive.........this is bcoz its in a protic solvent........and in protic solvent chloride ion acts as a betr leavin grp dan iodide ion..
1arey this is an elemination reaction not substitution in 1 after removal of electron
the carbanion formed is more stable due to gud -I effect of Cl
1guys mughe thoda doubt aaraha hai . whether more reactive means which has more rate of reaction ?
If yes then second one is more reactive no ? as rate of formation of two is more no ?
leaving group thing .
forgive boards ka karte karte the dimag kharab hogaya hai .:(
1how can u say that rate of reaction of 2 is more sri
u r talking about leaving group but in elimination we hav to first take out H+
then see which intermediate is more stable obviously 1st one
the beauty of this Q makes it a bit confusing [1][1]
