Valence Bond Theory (VBT) is a model used in chemistry to describe how atoms combine to form molecules. It provides an explanation for the formation of chemical bonds, emphasizing the role of atomic orbitals and electron pairings. Here are some key aspects of Valence Bond Theory:
1. Atomic Orbitals:
- VBT assumes that atoms use their atomic orbitals to form bonds. Electrons in these orbitals can pair up to form a chemical bond.
- The most commonly involved orbitals are the s, p, and sometimes d orbitals.
2. Hybridization:
- To explain molecular shapes that cannot be accounted for by pure atomic orbitals, VBT introduces the concept of hybridization.
- Hybrid orbitals are formed by mixing different types of atomic orbitals on the same atom (e.g., sp, sp², sp³).
3. Overlap of Atomic Orbitals:
- A chemical bond forms when atomic orbitals overlap, allowing electrons to be shared between atoms.
- The extent of orbital overlap determines the strength of the bond.
4. Sigma (σ) and Pi (π) Bonds:
- Sigma bonds result from the head-to-head overlap of orbitals. They are the first bonds formed between two atoms.
- Pi bonds result from the side-to-side overlap of p orbitals and are found in double and triple bonds, in addition to the sigma bonds.
5. Localized Electron Model:
- VBT treats electrons as localized between two atoms in a bond, unlike Molecular Orbital Theory, which treats electrons as delocalized over the entire molecule.
6. Resonance:
- Some molecules can be represented by more than one valid Lewis structure, known as resonance structures.
- VBT accounts for resonance by considering the molecule as a resonance hybrid of multiple structures.
Valence Bond Theory provides a fundamental framework for understanding chemical bonding in terms of orbital overlap and hybridization. While it has limitations, especially in explaining complex bonding scenarios, it remains a valuable tool for studying the structure and behavior of molecules.

Thank you sir for teaching this concept
WOW!!! Table Tennis! AMAZING!
Thanks Sriritwik!
I really love your class and teaching but please 🙏 can you make a video on empirical formula and electronic configuration?
As a table tennis player Using a tennis ball with a table tennis racket is outrageous 😂💀
Jee aspirants need teacher like you sir❤ tq so much.
Sir , my request is to- concentrate more on 11th and 12th cbse syllabus
Really superb explanation sir..... I understood it very well..... Thank you very much sir🙏
Woohoo!!!!Time to understand the concept🎉
My exams are going to start from 1st august
I am glad that i found this video..😊
yaayyyyy!!! finally i can understand it easily!!!
Glad to hear that 😊
Thank you a lot
SIR! The Geometric Shape Of Water Molecule Is Not Giving The Exact V-SHAPE, But It's Obviously That Water Molecule Has A V-SHAPE! So,I'm Confused Seriously, Please I Need Explanation Sir.
Thank You Sir,
Hope My Question Will Be Answered!
Plz explain optical fibres in physics and hybridisation and types of isomerism in chemistry.
Thanks
you are crushing it doctor
BLOOPERS IS THE BEST 😂😂🤣🤣
Ha ha 😊
Excellent explanation
Sir please upload hybridization, vsper theory,and mo theory please 🙏🙏🙏🙏
Thanks you sir keep it up
Thank u very much sir for explaining it... You made this topic very easy for me sir
Sir please explain about gradient and laplacian and divergence theorem please sir🙏🙏🙏🙏.......
Thank u sir
Thankyou so much sir for a good explanation
This VBT is in our weekend exam syllabus
and scrolling for a good explanation video , finally found it
Now I can write my exam confidently 🙂🙂
based on the question there are 6sigma bond and 2pie bond
Thanks sir for your excellent hardwork for us😊😊😊😊😊😊😊😊😊😊😊
You're always the best!
Sir i am about to enter university what are the things i most know before going to university because i wamt study medcine
I am first
Thanks for watching 😊
I was waiting for this video . Thank you very much sir😊
Base on the question, they are 2 pi bonds and 8 sigma bonds. Think?
Hello sir
Best explnation i know your videos because of my teacher

Sir are you bengali
Plz reply sir😢
