What is syn and anti periplanar

please accept the answer if you got it 🙏🙏

in case of E1 any syn or anti addition occurs or not

no, here carbocation is formed

so only in e2 case anti elimination occurs

yes

syn mean bond angle between H and Lg is 0 and anti mean bond angle between H and LG is 180

got it??

so in case of e2 syn elimination can't occur

yes, here anti elimination takes place

only Cope elimination gives syn elimination

cope elimination means

The “Cope Elimination” is a reaction where an amine is oxidized to an intermediate called an “N-oxide”, which, when heated, acts as the base in an intramolecular elimination reaction.

syn elimination

got it??

how many types of eliminations are their ...

E1,E1cb,E2, cope elimination

so cope also under goes in this elimination type ..?

yes, it's the part of elimination reactiona

It is also known as Ei elimination

i think you have heard about Ei

ok pls ...explain those lines which I m attached with why questions why here mention syn periplanar

wait..

like intermolecular substitution sni ei ...is same or not ?

SNi and Ei is different things

here they are only telling that elimination occur via syn or anti manner but it doesn't mean they say that E2 is syn and anti both. E2 is only anti elimination

so why mention syn periplanar

they tell only tpe of elimination syn or anti

ohhh ...ok

got it😊??

one little doubt

yes, please

I know sni and Ei are different just I m saying that sni is intermolecular substitution and Eni is intermolecular elimination ..in these way I m saying it same

can u give ur video lectures...?

yes, Ei mean internal elimination just like SNi

yes, https://youtu.be/cVlM74yhzYA

please mark the answer if you really satisfied with my way to explanation.

I m not asking about this lectures I m asking about ur video lecture

no, I don't have my video lecture

ohhh but ur way of explanation is so helpful ..if u do any video lectures it must be very much helping ...🙏🙏

yes, I'll provide you 🙏

tq very very much for this kind helping...🙏🙏

it is intra or inter in case of cope elimination

hope it helps😊

Dihedral angle should be 180⁰ in anti periplanar

Simun do you know dihedral angle ? We use this in newmann

See this anti periplanar

See this. Dihedral is zero for syn elimination

what is dihedaral angle

Newman conformation do know?

yes

but in case of e2 elimination only anti elimination occurred so why here syn elimination

Syn elimination termed as Ei not E2

E2 is always anti periplanar

https://youtu.be/d2i3uU_s1XU. For dihedral angle. Short video. see it

but the image I attached with my question is written both syn and anti periplanar

can u explain those lines which are written in the image ..

I was checking Simun

Which book is this Simun?

E2 is anti-periplanar only Simun. In the image it is written that elimination can happen in two ways.

I have provided explanation Simun

Simun any more question?

can u provide u r video lectures also or not ??

Ofcourse Yes. Please say your topic

about chemistry of reactive intermidiate

and can u give ur video lecture for organic for imp ...for jam pls pls ...🙏🙏🙏🙏🙏the tricks the basics ...

Simun chem academy providing free lecture for IIT JAM. please watch that

can u give me link of this

r u from chem academy

yes Simun
