[@jaweriarana4526]

There are some rules of drawing molecular orbitals. You are not following them. Can you justify your diagrams? Following are the rules: A single node must cut through the centre of the molecular orbital. Two nodes must be placed an equal distance from the centre (i.e. such that they are balanced with respect to the centre) Each successive energy level adds an extra node. Note that an orbital with an odd number of nodes will always have one node in the centre.

Thank you for the video, Ma'am. I just want to bring to your notice that psi 3 should have symmetry.

In photochemical reaction of 1,3-butadiene psi 4 will be lumo

[@manishathakur509]

No...she is right..psi 3 will be LUMO...lowest unoccupied ...name se hi idea lg jata h itna

Didi for 1.3- butadiene app nodes ko jara dekhiye... For ¥2 one node present and node will be middle of 4 orbital... That is in between 4 two are same side and two are opposite side... Node present between this....

A new day with a new topic ...maam as u said I m afraid of organic tough I choose this one to continue...good morning ...have a nice day...love and respect from Assam.

[@jaishreesinghbaghel647]

Ma'am HOMO and LUMO of the wave function cannot be same that you represented in the molecules. These molecules will become highly reactive and unstable if this happens.

[@madhvisharma747]

But mam, 1st example ethylene , in comparison to state function si 2.. Si1 is lowest unoccupied molecular orbital in excited state.

[@madhvisharma747]

Now I can realize. In excited state homo & lumo will be same.

[@varshagupta4041]

Mam why si 2 cannot be considered LUMO in case of photochemical reaction since it also has one unpaired electron like si 3

[@jaweriarana4526]

She is doing wrong

[@nareshguptaorchhotanirahuw958]

Yes.. the total number of pi bond in ethene is 1 not 2 .....she is getting mistake 🇳🇵

[@GauravSingh-uz8of]

@@nareshguptaorchhotanirahuw958 yes pie bond is 1 but pie electrons are 2

[@somyamishra2023]

mam....correction plz...After assigning + and - notation ..formed orbitals must be symmetrical

[@ashutosh_mishra_lko]

Exactly..

[@innamarizviinnamarizvi4722]

Thank you so much ma'am ....you are best teacher of chemistry

[@kryptonx3240]

Mam the node should be generated in the very symmetric way. But in case of 1,3-butadiene the way you generated the node in si2 and si3 is not the most symmetry way. I think in si2 the node will come in between lobe 2 and lobe 3 and in case of si3 it will come aftr lobe 1st and 3rd one. Plz clarify it.

[@f47.priyabratadas49]

Didi,generally node chooses symmetrically in orbital wave function, every book following this convention

[@jupitarhossain3203]

Yes absolutely

[@nidhiparmar1286]

Ya right

[@chemspy3445]

Yess hme c2 and m symmetry ko bhi consider kerte huye lobes me + and - dena h 1,3 buta diene ka psi-2 me lobes sahi nhi draw huye h

[@bithikamaji6562]

Lumo of 1,3 butadiene will be 4 th energy level..the 3rd energy level is filled up by 1 electron so how can it be lowest "unoccupied"??

[@anshu263]

In excited state 3rd energy level is filled up by 1 electron so we can say LUMO

[@MintmadeFashion7]

Ya I'm books too si 4 is lumo,, so confusing man

[@deepakprajapati9251]

Mam in orbital diagram nodes should be placed on symmetrically but here in phi 2 nodes are asymmetrical filled, plz have look on it.

[@alfiyasurve4300]

What to say .... watching 1st video of ur channel and m fan of ur teaching....

[@_randomyoutubeuser]

Mam... your videos are very complete but try getting some technical assistance for voice echo and also a humble request... Please step aside when instructing so that we can still see what's written on the board... Or the other way around... Please get a bigger board.🙂 Anyways, keep up the work... Its really good.👍🚩🇮🇳🚩

in psi 2 node should be in the middle , not at left side which you did . if a wave is constructed on this basis , then you can clearly see that node should be in the middle not at right . if i am wrong then please comment so that i can easily rectify my mistake .
