chalte chalte elimination vs subs

prop1,2 diene and 1-propyne
why do u want sn2...alc koh is not meant for sn2 ! the sn2 products would , however , be prop 2 ene 1,2diol

for 1 mole of alc KOH we get 1 chloro propyne

why not ? then you mean to say that a cumulated system is stabler than a triple bond ?????

i am soory the question is a bit wrong editing it!!!![2][2][2]

edited!!!now ok debo can give the answer!!!~

i thought that ALC. KOH will attack the unhindered carbon first and then the answer would be 2 chloroprop-1-ene!!!

think abt it.......or whats ur logic???

what happened debo

alc KOH prefers E₁ reaction mechanism thereby going for the more stable carbocation !
