@prajith: here is a clue dude, u hvae to consider not only lone pair availability on hydrogen but also the approachability to that lone pair. and also solvation energy of the amine should be considered.
I wud go wid B...
d wud hav bn my 2nd choice...
prajith ans kya hai
ya .........i too think so richa.........but was having a confusion.......
Ans :
d) aniline is the weakest base because in this case the electron density present on nitrogen will be donated into the ring so it will be less available to abstract proton
i told B coz Ph has -I effect.....
so basicity decreases....
pata niahi y os ans D?? [2] [7] [12]
wats da source of da question.... r usure on the ans?
yah but here, NH isnt directly attached to the benzene ring.... then how can it b in conjugation?
i may b wrong
