    ab check kro

    eduncle-logo-app

    -I is more on ortho than para please correct this statement un the picture.

    eduncle-logo-app

    acidiy-- meta > phenol> ortho> para

    eduncle-logo-app

    sir picture fr send kr di

    eduncle-logo-app

    do

    eduncle-logo-app

    plz send it again

    eduncle-logo-app

    eduncle-logo-app

    ok

    eduncle-logo-app

    sir para pe ,- I negligible hota isiliye u wrote only ,+r

    eduncle-logo-app

    yes, because distance jada he na OH se so less hota he

    eduncle-logo-app

    sir + r nh2 Ka kyun Jada hai och3 se

    eduncle-logo-app

    because N ka EN O se km se so easily lp donation hoga to +R jada hoga

    eduncle-logo-app

    explain kr do

    eduncle-logo-app

    kha doubt aa rha he

    eduncle-logo-app

    sir one more thing ...meta pe always - I,-m ,- r lgega

    eduncle-logo-app

    if yes then why

    eduncle-logo-app

    because jb app resonating structures bnayege to +/- charge o and p pr hi ayega

    eduncle-logo-app

    usse kya

    eduncle-logo-app

    usse kya hoga

    eduncle-logo-app

    usse ye hoga ki ortho or para pr electron density ya to bd jayegi ya km ho jayegi meta k compair ms

    eduncle-logo-app

    sir samagh ni aa rha

    eduncle-logo-app

    mean agr +R effect wala group he to o and p pr - charge ayega or -R group he to o and p pr + charge ayega mean dono type k group o and p pr jada effect dalege

    eduncle-logo-app

    sir ...+ r ke according b,c >f,g se

    eduncle-logo-app

    +R ortho or para pr work krta he to ab hm -I se compair krte he -I ortho pr jada ho so ortho para se jada Acidic hoga na

    eduncle-logo-app

    sir - I HM kyin Lete Hain ....we know - r> - i

    eduncle-logo-app

    r ko hi Lena Chahiye n

    eduncle-logo-app

    sir answer plz

    eduncle-logo-app

    yes -R ko hi lege agr ortho or para pr he to but meta pr to only inductive effect lgta he na to r kyo lege

    eduncle-logo-app

    reason btaya na ki jb koi charge hi nhi ayega meta pr to R kyo lgega

    eduncle-logo-app

    sir ....ik cheek poochni hai ....generally jiski normality pta Hoti hai usko we kept in burette but in double titration this doesn't matter why

    eduncle-logo-app

    Between all 7 or separately for amino and methoxy?

    cropped5006518784509450886.jpg
    eduncle-logo-app

    sir between all 7

    eduncle-logo-app

    check above image shweta

    eduncle-logo-app

    yes between all these i am explaining

    eduncle-logo-app

    first i do separately all these

    eduncle-logo-app

    ok sir thanku 🙂

    eduncle-logo-app

    shweta you can too relate these... nh2 has more +R effect than Och3

    eduncle-logo-app

    if doubt please ask

    eduncle-logo-app

    sir Mera pe -i why

    eduncle-logo-app

    ortho para directing group hote hai nh2 and och3 due to lone pair on oxygen and nitrogen so +R

    eduncle-logo-app

    and due to electronegativity of oxygen and nitrogen ye -I effect show krte hai jo meta position pe hote hai

    eduncle-logo-app

    activating effect ortho and para position pe exist krte hai and deactivating effect only meta pe

    eduncle-logo-app

    sir means - r, -m bhi meta nhi exist krenfe

    eduncle-logo-app

    haa...deactivating meta pe hi exist karte hai

    eduncle-logo-app

    sir + r ortho Ka Jada kyin hai + r para se

    eduncle-logo-app

    coming to ortho and para, amino and methoxy group is more closer to O- than in para. Therefore more +R effect is experienced the charge making it less acidic than para

    eduncle-logo-app

    doubt clear nhi hua shweta

    eduncle-logo-app

    phle doubt clear kar lo ...jo doubt hai pucho...tm aadha adhura puch ke chali jati ho

    eduncle-logo-app

    ek question ek baar me clear kar logi achha rahega na

    eduncle-logo-app

    sorry sir...sir I think ortho metoxy phenol is more acidic than para metjoxy phenol
