Molecular Orbital Theory is primarily used to explain the bonding in molecules that cannot be explained by Valence Bond Theory.A linear combination of atomic orbitals or LCAO is a quantum superposition of atomic orbitals and a technique for calculating molecular orbitals in quantum chemistry. In chemical bonding theory, an antibonding orbital is a type of molecular orbital (MO) that weakens the chemical bond between two atoms and helps to raise the energy of the molecule relative to the separated atoms. Such an orbital has one or more nodes in the bonding region between the nuclei. The density of the electrons in the orbital is concentrated outside the bonding region and acts to pull one nucleus away from the other and tends to cause mutual repulsion between the two atoms.This is in contrast to a bonding molecular orbital, which has a lower energy than that of the separate atoms, and is responsible for chemical bonds.In this video we will cover:

Jab bhi doubt aata h...aap turant bolte ho, 'ab aap soch rhe hoge.'...u understand ur students so well...#concept hua crystal clear

[s.mgamer...]

Tomorrow is my chemistry exam and i was worried about this specific topic as it wasn't​ uploaded on your channel and suddenly you uploaded it 😃😃

[guessmyname]

Who want that mam should provide notes of every lecture in the form of pdf

[Choudhary_mn]

We can't find.... A better chemistry teacher than you ♥

[RashidaBegum-nx]

Thank you ma'am, my textbook finally makes sense now ...😂

[sunitajaiswal]

This topic was completely out of my brain in my Coching but i was not worried bcs i know it will be crystal clear after watching your vedio.

[baldeepsingh]

Its a great blessing to have a teacher like u....

[amrutk]

HER COMELINESS TEACHES EVERYTHING THAT COULDN'T LOAD UP FOR A BEGINNER HE MAY GO A FABULOUS RANGE. GREAT JOB AND ❤️ FROM MY SIDE
U WERE THE BEST....
U R THE BEST
U WILL BE THE BEST MADAM❤️❤️🎉

[srishtiyadav]

Loved the series ma'am.. I followed each and every video and now I can say that chemical bonding is one of my strong topics. You made me love chemistry which I used to hate earlier... Thank you so much Ma'am 💕💗

Mam aap itna acha itna acha pdhate ho na ki mujhe word hi nhi milte likhne ke amazing and super duper explanation
And your way of teaching is very different than others and just wow
thanks to God ki unhone apko hme diya and thanks to you also aap bhi to hme itna acha study krvate ho 😀

[ashupatil]

Tumhala jevde dhanyavad dyave tevde kmi ahe tumhi srv subject kiti chan padhyatine getat ks krtat mam tumhi he tumhi kharch khup motya genius ahat tumcha sarkhya mam chi ajj kup garaj ahe tumchya sarkhya mam aslya trr koni student depression mde janarch nhi mi jamale trr tumhla betaycha prayant krel mazi khup ichha

[tahirimran]

Thankyou so much ma'am your lecture is really very very helpful may you be blessed by all you desire ❤❤❤

[balvinderkour]

Finally completed my chemistry syllabus for half yearly all due to roshni mam.. Thankuhh so much mam for such wonderful explanation

[harpreetkaur]

Wonderful explanation ⭐⭐⭐⭐⭐ thank you mam. I understand this concept in one time because of you.

[AvtarSingh-gqmc]

Fabulous way of teaching 👌👌👍may god bless you mam ❤️🙏 really u r best teacher of chemistry 👌

[zainab]

Mam u r such a Mam i don't know how to thnks uh for making concept Cristal clear.... May Allah give uh very life and give uh all what ever uh want 😘😍

[shrutitripathi]

At 21:12 the constructive and destructive interference are written on opposite diagrams.

[bestbudgies]

Mam thank u soo much the molecular orbital diagram was tough to me but after seeing this vedio it was easy to me... Keep going mam...

[silentsucess]

Thanks a lot ma'am. Now all concepts are crystal clear with zero doubt.

[MAYUR]

🙂❤️Mam, how well you taught this chapter. Thank you🙂❤️
