general doubt in SIR/OOPS
why will every bulky group create hinderance at equal amount if their sizes r different??
explanation to be given with surety plz!!!

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.
VShort answer: "They don't
VBulkier groups create more steric hindrance
VSay NO2 would create more hindrance than COOH
VSay SO3H would create more steric hindrance than both of these
VWhat we study in SIR and all is mere approximation such that after a group is bulky enough
VIt creates enough steric hindrance to change the plane of the group on ipso carbon (the one on the ortho position of which the bulky groups are)
VDo you get it?
SYh got it
SWas thinking about this only but i didn't know if it is rlly approximation or something else
VIt is
There are values called A values
There are values called A values
VThey tell you about how bulky a group is
VAlthough this is very much like inductive effect order
There's no exact or definite order
There's no exact or definite order
VEverything depends on the reaction pathway and the conditions we enforce
SWait um... we'll see after 10 mins
SSry 
SOkay so there r significant differences in oops due to different different groups ??
VThere could be yes
VDepends on group
SOoo
SNot in general cases?
SOut of jee syllabus??
VDepends on the case tbh
VI don't think you really need to differentiate much in jee
VJust treat any bulky group as a bulky group
VIt would mostly work
SOk ok
SUm...kch name aise bta skten h toh bta dijiye btw

VVo nermal or picchi dekh rahe hain
SBtaiye btaiye
VNaam matlab?
VKiska?
SName some such exceptional bulky groups ifyk
SWhich show unusual behaviours
VNaah I don't really remember any from the top of my head
VCase to case depend karega as I said
VMostly won't make a difference
VBulky is bulky
SOk fine fir
