Note for OP
+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.hn par methyl ka orientation same nhi hai
ik me bromide ka alg hai
wait ig b isnt cis
yeah b mein trans hai hai i got that part
only problem is with A part
in a and c the orientation of br and me is diffrent
a nd c both are cis
wait a min
waiting..
2 min ye solutions ka karlu pehle phool ji ka
uske baad ill look into my notes
ok to firstly
it is reacting with alc KOH
means yaha E2 follow hai
looking at structures
a)
br is axial
methyl is equatorial
in b)
br is equtorial
methyl is axial
and in c)
br is axial
methyl is also axial
iski stability kam ho jayegi relatively to a
and this is trans so isko to we cn leave out it will have diffrent products
arent u saying is backwards , Br is equatorial
huh? what
no
here Br is equatorial and Me axial


this is how it works
thats what i am saying...
so br is wait
oh yh
uhh lemme think
take your time
in a
br is eqitorial and
methyl is axial
in c br is axial and methyl is equitorial
yes
u got that right
so both of em are cis
and a will require ring flip to react right?
but c wont
because usme it is alredy axial
thht yes
no , we have to find products in the given compound only
A and C are like this

yh tht i know
but during rxn usme ring flip lagega na?
tht im sayin
i think lagega
a ko
nahi u cant flip
and agr flip lagega to kam feasible hoga e2 c ke comparison me
why?
because rxn has to be done in given compound only
like in that very state
ok but agr usko react karna hai a ko it will need a flip hypothetically
but we are not allowing
why tho
to uska feasilibility kam hoga
equatorial br doesnt react ??
i think lagega i am not sure
i have done a question jisme laga tha
thts why
ohhh
maybe
i think kisi aur se bhi confirm karlo to aacha hoga
but mere hisab se isi karnn hoga
aans key mein likha hai
no rxn because LG in equatorial
yeh rule patani kahan se aaya
rest of the prods are fine
