Valence Bond Theory || VBT || Coordination Compounds || Complex Compounds || Coordination Chemistry
Many approaches have been put forth to explain the nature of bonding in coordination compounds. One of them is the Valence Bond (VB) Theory. The Valence Bond Theory was developed in order to explain chemical bonding using the method of quantum mechanics. This theory primarily focuses on the formation of individual bonds from the atomic orbitals of the participating atoms during the formation of a molecule.
According to the valence bond theory,
Electrons in a molecule occupy atomic orbitals rather than molecular orbitals. The atomic orbitals overlap on the bond formation and the larger the overlap the stronger the bond.
The important postulates of the valence bond theory are listed below.
1.) Covalent bonds are formed when two valence orbitals (half-filled) belonging to two different atoms overlap on each other. The electron density in the area between the two bonding atoms increases as a result of this overlapping, thereby increasing the stability of the resulting molecule.
2.) The presence of many unpaired electrons in the valence shell of an atom enables it to form multiple bonds with other atoms. The paired electrons present in the valence shell do not take participate in the formation of chemical bonds as per the valence bond theory.
3.) Covalent chemical bonds are directional and are also parallel to the region corresponding to the atomic orbitals that are overlapping.
4.) Sigma bonds and pi bonds differ in the pattern that the atomic orbitals overlap in, i.e. pi bonds are formed from sidewise overlapping whereas the overlapping along the axis containing the nuclei of the two atoms leads to the formation of sigma bonds.
In this video I have discussed about the Valence Bond Theory for complex compounds / Coordination Compounds. I have explained the different hybridizations and the geometries associated with them. The difference between VBT for normal Covalent compound and Complex compound is explained with an example.

Itna detailed, crisp & time efficient lecture VBT par kahin available nahin hai... 👍👍👍
Disclaimer- Is video se apka valence bond theory of coordination compound ka concept ekdam crystal clear ho jayega... Love u sir .. Found the teacher that matched with my teacher of imagination in clearing one one doubt very clearly ♥️
ap best padhate ho sir, u r the only teacher i prefer in youtube to understand max topics of chemistry.
I read this topic from many books from many platforms but literally which knowledge I got today is epic. It’s because of the way of your explanation sir. Jo rydem hota h na ek padhane ka only you have that type of talent.
Very nice teacher ...Best teacher of chemistry all of world ..plz statistical Thermodynamics , Quantum chemistry Ky leacture uploaded kr dy
dispite studying hybridization so much, today is first time I have understood it completely, thanks
Thank you so much sir... Aaj me VBT really me samajh payi
Mashallah very nice practically understanding lectures
IIT JAM Ki preparation sir aap krva rahe hai Sir hum form apply kiye hai ,but samajh nahi aa raha h best study material kaha milega ...help me sir 🙏🙏🙏
Sir you are best teachers
Sir your video helpfully and concept easily understand
One of the best videos on this topic :)
Sir u r like rising star for me😅😇 there were frustation,stress,tension coz its exam's time or kch smjh nhi a rha hota tha then i got ur lecture video,or mne apky chennal ko subscribe kr lia or jo jo topc smjh nhi a rha hota tha wo search kia....nd i can't explain Sir... life smooth feel hny lg gyi itni bri tension khtm hny lg gyi Fsc se ab Msc tk koi esa teachr nhi mila jski itny achy tareeqy se smjh ayi ho finger tip pe sb yad hny lg gya...i don't know would it seem awkward but it feels like salman's khan kick movie that i got kick which I was desiring for...Dill se dua niklti hai apky liye.....bundle of best wishes ✨💖❣️
Best 💕💕teacher 💕💕of India.. 😊😊
Nice video cleared every doubt 👍👍.
Sir you are just amazing in clarifying the concepts👏
bahut he zabardast thanks sir
Just wow , aaj hmare coaching me padhaya kuch smjh nhi aaya , 🔥🔥🤗🤗
Amazing explanation❤❤
Good explanation sir thank you
Such a great vdo ....
Best explanation.. 👌
Very usefull lecture
this was incredible
Superb 👌......
Thank you so much. ❤️
Best explanation 👍👍👍
thank you sir. really sir bahut acha samjaya hair
Very nice lecture Sir ....💙👏👏
Thanks sir aj mujhe VBT. Aa gya
Mashallah very nice excellent
U r just awesome sir
Sir please make vedio on quantum chemistry ...its hard to understand on books
Ek no. 🎉
Thank You Sir👍🙏
Thank you sooooo muchhhh💕💕
Excellent 👍
Thanks 🤞🤞u so 😊😊much 😍😍my best sir ❤❤
Outstanding sir
Excellent 👌. Mashallah. Thank you 💕 so much
thanku sir
Sir,please start quantum chemistry. It's difficult to understand.pls start quantum, pls pls pls
Woww 😮
It would be a great favour on a chemistry learner like me if someone could please share me the link of the next video!! THANKYOU IN ADVANCE!!
👍👍
Crystal field theory And ligand field theory ka video v dalya sir
Love u sir 🙏🙏🙏🥰🥰🥰
Upload crystal field theory and M.O.T
😊😊😊
Sir aek detailed video banaye Schrodinger wave equation
