se after solvosis the charge on sulpher is - which is stablize by benzene ring by resonance

ya....your ans was rite but i dont think steric effect plays any role here.It's basically due to "neighbouring grp.effect"

yes..... of course.

I guess all of you have different reasonings
BUT the correct ans is B i.e I >> II > III

The explanation's coming ..........

dude !
wherez benzene?
it is cyclo hexane !!!!
u donnno diffn betn
benzene n cyclo hexane o wat ?
c6h6 benzene
c6h12 cyclo hexane
where can u see double bonds in CARBON?>? haaaaaaaa ?
either c or d
i go with
C

n dude !
ter is no benxene ??
kaha pe bbenzene dikh raha hai be ??
it is cyclo hexane !!!!!!!!!

ITS RIGHT
BETWEEN C N D
MANIPAL
BUT I THINK ITS C
Y U THINKK D?

rkrish pls tell da answer !!!!!!!

accordin 2 meh i feel answer is b cuz elimination takes place in trans way so 1 structure mein trans hai .so itna hindernce ni hoga weras last mein steric hindrnce hoga

corrct meh if m wrng

ab mere vichaar bhi sun lo ghante ki behass ke baad
the fight is b/w C and D

i think
the answer must be D

my reason C6H5 jo hai woh solvolysis mein hindrance daalega

benjene is non polar na and doesnt solvate easily

Solvolysis is a special type of nucleophilic substitution or elimination where the nucleophile is a solvent molecule.
For certain nucleophiles, there are specific terms for the type of solvolysis reaction.
For water, the term is hydrolysis; for alcohols, it is alcoholysis; for ammonia, it is ammonolysis.
i think its C ?
CHLORINE WILL not get easily brekoff
so as it will require solvents and other special reagents !
while 1 n 3rd r almost ~same
so........lone pair of e- on cl n as well due 2 lack of resonance it will adjust by elimination
so opti9on ONLY
C OR D
BUT FINAL I THINK SOO
C ?
is it right i just think so , pls scrap me if u know final !!111

Thats wat i was just thinking...u might been confused b/w the two!!

rkrish ·

and wat do u mean by " H n Cl jyaada water molecules ko attrct karenge " .
Solvolysis hai ..toh Cl has 2 b removed.

Speaking of lesser charge density , wat abt the electrons on S.. of PhS- ??
