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...

the 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..

thnk abt abstraction of H+ //

arey 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

yes :)

nice q sky

copied one dear :)

but yes! its nice :)

guys 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 .:(

how 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]

and thats why rate of reaction of one is more

oh haan rds hi bhool gaya thanks yaar. :)
