basicity

woh mera bhi ans tha gagar bhaiyya . lekin values nahi agree kar rahe hain .

and @ 8X10 . ortho effect . said by tapan gives u the answer.

wat the fu_k man................
morreson and boyd paagal hai. ye loge saath mein reason kyu nai dete. chemistry mein concepts hote hain ya nai??????????????????????????????????????????????????????????????
CHEMISTRY SUCKSSSSSSSSSSSSSSSSSSSS

i think 1>3>2>4

tapan has hit the nail on the head when he used ortho effect I had thought it's applicable for only benzoic acid :(

and @ sky maafi chahta hoon for leading wrong way . :(

see ,this is what I got from Morrison Boyd . pg 860 .
Kb ( in powers of 10^-10)

Aniline - 4.2
ortho - 2.6
meta - 5
para - 12

which measn that tapan and sky are right .

I wrong . :( :( pata nahin chem me hi aisa mistakes kar raha hoon . 3-4 days se kuch theek nahi chal raha hai

corect ans is 3>2>4>1 . given by tapan

@ sri.. who is rit now ????????

tapan or u?????

but priyam said dat d ans given is para>meta>ortho

1 is least basic due to large steric hindrance....
in 3 both hyperconjugation and inductive effect is there......
2 has inductive effect......
4 is only having ortho effect...
thus 3>2>4>1

explain tapan ...plz.....i think i m really gooffing thing up today!!:(

i m thinking totally opposite

yes tapan

but the reason?

exactly the same order as u ve given in the ques - decreasing order

yehe!!! that means wat i told was rite!!! 3,2,,4,1

it is due to +I effect...nearer the -Me group more +I effect

sry guys made a mistake .

I don't agree with deepanshu hurry me galat kar diya :(
. it's 1>3>2>4 .

dekho bhai . tumko kisne kaha ki ortho effect . means you just increase the acidity of the group present in ortho position . that's wrong will post why later gtg for now . and b/w try my organic problem . in general chem forum. :)

oh shit.... yes it decreases... so donating capability inc...

shit.

thanx sri..

i always mess up in the last step!

Sri da, ORTHO - EFFECT inc. acidity

=> decereaese bascitiy

in Para Postn we hav both R & I effefects operatin in meta only I

deepanshu is correct :)

@ sky . if it goes out of plane what happens to resonace of lp wiht the benzene ring ? inc ya dec ??

so what happens basicity inc ya dec ???

I'm leaving the rest to you

more basic means shud lack in electrons as they accept ele.

rather, opposite.

more basic means they give electrons easily.

which one is more basic? NH3 or H2O ?

think.

plz help me wit acidity and basicity

sum 1 correct mah concepts ......[2][2][2] my ans. is nearly opp/ to others /////
