1 will show least as there will be steric hindarnce and they will go out of plane ..
-Me is not that large group like -Ph to go out of plane
i feel deepanshu is rite
-Me group nearer ...more availability of the lone pair...it wont delocalize
1woh mera bhi ans tha gagar bhaiyya . lekin values nahi agree kar rahe hain .
and @ 8X10 . ortho effect . said by tapan gives u the answer.
1wat 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
1tapan has hit the nail on the head when he used ortho effect I had thought it's applicable for only benzoic acid :(
1see ,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
1@ sri.. who is rit now ????????
tapan or u?????
but priyam said dat d ans given is para>meta>ortho
1aniline has least basicity that's for sure .
and among the isomers . orhto has maximum , then comes para , then meta
so 1>3>2>4
13oh got it now....
i was taking rubbish yesterday[3]
para>meta>aniline>ortho
11 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
13explain tapan ...plz.....i think i m really gooffing thing up today!!:(
i m thinking totally opposite
13exactly the same order as u ve given in the ques - decreasing order
13it is due to +I effect...nearer the -Me group more +I effect
1sry guys made a mistake .
I don't agree with deepanshu hurry me galat kar diya :(
. it's 1>3>2>4 .
1dekho 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. :)
1oh shit.... yes it decreases... so donating capability inc...
shit.
thanx sri..
i always mess up in the last step!
21Sri da, ORTHO - EFFECT inc. acidity
=> decereaese bascitiy
in Para Postn we hav both R & I effefects operatin in meta only I
1deepanshu 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
1more 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.
3sum 1 correct mah concepts ......[2][2][2] my ans. is nearly opp/ to others /////
1i agrree with tapan..
1 will show least as there will be steric hindarnce and they will go out of plane ..
