conjugated systems

explanation of conjugated systems and example problems

[@V_MA]

You have done a great job with explaining of the Conjugated Systems concept. Thank you a lot!!

[@a.aldukhail8696]

Thanks for making this video available. I am a physicist with no good chemistry background, but still understood your explanation. Thanks.

[@sidi1128]

Thank you so much for this clear explanation!

[@meltemtutar4673]

Thank you! I was always getting conjugation and aromaticity mixed up. Watching your videos I now understand! I also got 12 atoms and 14 electrons. for the exercise at the end.

[@natalie-rosewilcox7650]

awesome at explaining! thank you from Cornell University

[@phenlism]

Thank you! Very helpful (:

[@LanNguyen-iu3oe]

this helped me a lot--thank you!

[@mdmushfiqurrahman3832]

Thanks for the video 👏👏👏

[@2012farfar]

Conj. Atoms =12 Conj e- = 14 because one of the last N is directly attached to the double bond, so that is a commulated system. Is that correct?

[@zainabsarmad8031]

is LUMO nd HOMO same for ethylene in photochemical condition i..e cy 2?

[@karennavarro567]

OMG thank you so much. I was so lost in my class and now I totally get it.

[@shehrozetalat2617]

karen navarro.. Is there any difference between extended p system and conjugated p system?

[@muhammadsohaib2976]

Very helpful thanks :)

[@ran9628]

great video, thanks.

[@monae6868]

Wonderful!

[@yyc02]

that's really helpful!

[@radheshah2468]

what will be the answer to the problem?

[@shehrozetalat2617]

Is there any difference between extended p system and conjugated p system?

[@alderamin1402]

Can you tell the answers please What I found is 12 conjugated atoms and 14 conjugated electrons

[@louisitamerryln902]

Please, are you concluding that every conjugated system becomes or forms sp2 hybridized? I'm asking in reference to how the sp3 nitrogen became sp2 after a pi bond was introduced adjacent to it. Thank you.

[@Mh37894]

I cannot thank you enough.

[@grantjimenez9032]

Thanks! This helped!

[@isaacsamuel9520]

So, Conjugation, in essence, is just 3 or more nearby (And Parallel) Pi bonds coming together and forming an single entity. Am i wrong?

[@charmanteb2012]

Wow, thank you!

Thank you!

[@captivatingmindsvisible]

What kind of software ,he is using for this lecture delivering ?

[@esraa9796]

Thank you very much u r awesome

[@khursheedahmad6911]

Love...... ❤❤❤❤

[@alaaalnadhary1773]

Perfection

[@eduardovasconcelos8918]

thank you!!!

[@thangton1719]

Are these "p-orbitals" unhybridized?

[@SanaKhan-uu4kd]

Yes

[@annuallyannual9444]

God bless you

[@indigobreezy]

thank yu so much

[@zulamanavraj9669]

Thank you soo much .no one makes me understand this😭😭😭

[@FONK6969]

3:45 how does that only have 8 electrons? Doesn't every double bond have 4 electrons and not two?

[@27danike]

He's just talking about the electrons in p-orbitals.

[@zainabsarmad8031]

@@27danike is LUMO nd HOMO same for ethylene in photochemical condition i..e cy 2?

[@wejdandana2335]

thank you

[@monaash9492]

thanks

[@gabedaniel9948]

Late to class by 8 years D: Danget

[@gabedaniel9948]

Do you take late work?

[@spectrum5156]

late to class by 11 years, oops

[@aluo5577]

Answer for the last example is: Conjugated atoms: 12 Conjugated electrons: 16

[@codytrisler6630]

i got 12 conj atoms and 14 conj e- because the lone pair on the nitrogen furthest to the left is directly connected to a double bond so it would only count as 2e-. correct me if im wrong?

[@khaledalswayeh1098]

I got confused a little bit because he did not calculated the loan patron the second oxygen.

[@dixoncider8372]

I think it is supposed to be 11 atoms, 13 electrons

God... i hate organic chemistry 😢
