Nahi Bhai d option me dhyan se dekho yek hi alph hydrogen hai or rahi baat +I ki to hyperconjugation ka effect jyada hota hai as compared to plus I ke iss liye +H dominate kar Raha hai
At 28:40 .. I think correct✅ ans will be option 3rd because 2nd vale me ortho pr laga NO2 sterically hindered hai.... But para pr laga NO2 sterically hindered nai hai.... Correct me if I am wrong.......
bro steric hindrance tabhi lagega jab cl directly benzene se juda ho but cl ek carbon se attached hai and woh benzene se juda hai so ig jo sir ne bola woh sahi hai
28:40 , Answer is option (C) as in (II) & (III) " - M Effect is same as it is distance independent and is - I Effect is also same " , So reactivity comparison b/w (II) & (III) will be done on the basis of Steric Hindrance , and in (III) Steric Hind. is less and hence it will be more reactive , THANK YOU SIR !!

@@hellsterkun8764 lone pair ki wajah se repulsion hoga. toh isliye keh skte hain. ki jitne kam electron carbon ke pass hongey utna jyada stable hoga.
Sn2 mech mein carbocation nahi banta hai
cant we consider stearic hindrance the OH will face difficulty if 3 NO2 groups are present

Just Wow sir amazing.. ❤️🙏🏻
kitne acche se apne concepts ko btaya h!
28:42 ISKA ANSWER I THINK C HONA CHAHIYE BCZ -M IS SAME FOR ORTHO AND PARA ,
AND 3>2 due to hinderence and if I am wrong then why ?
-M to same rhega lekin Ortho me -I jyada lagega. Isliye 2>3 hoga
Same pankaj sir ke hisab sea c hoga aur sir nea alag explanation dia hea confused ho gaya mea
nhii nhi.. Steric Hindrance wala factor yaha play nhi karega kyuki cl ek carbon se attached h directly ring se nhi juda aur joh - I Effect h voh distance dependent hota h so ans is a
Haan inductive effect dekhenge ortho pe strong hoga para se
Both are having -M effect being on ortho and para then we check -I EFFECT ,which is distance dependent
