is very important concept in chemistry which student must understand and practice starting from high school chemistry.
Understanding of electronegativity is important which helps in reasoning of how different concepts like polarity in the chemical bonds , acidity and basicity of molecules ,flow of electrons in organic mechanism and many many more concepts of chemistry.
I have experienced that most of the students have a very weak base in electronegativity concept.
Many times they know the meaning of electronegativity but they don't know how to apply it on different types of questions.
None of chemistry text book has given electronegativity as a very big separate topic.
Just knowing the concept of electronegativity or definition of electronegativity will not make you comfortable with application of electronegativity in examination while doing chemistry problems .
I created five videos on electronegativity
with my more than 20 years of experience with different students all over the world.In every video Electronegativity concept is explained with the help of plenty of examples and there is a quiz in the end of the video.Electronegativity play list
These videos are important for any high school chemistry exam like AP chemistry IB chemistry SAT, IIT chemistry ,CBSE chemistry , college chemistry ,organic chemistry and MCAT or DAT chemistry
Electronegativity part 1
which is the introduction of electronegativity and explaining the difference electronegativity and electron affinity.
Here is the link of electronegativity part 1 video Electronegativity and meaning of polarity in bonds !

Electronegativity part 2
is based on trend of electronegativity in the periodic table
This is very important for high school chemistry as well as organic chemistry students.Trends of electronegativity in the periodic table is important to understand and explain many concepts of chemistry.

Electronegativity part 3-Polarity of chemical bonds
This video is dealing with range of electronegativity on the Pauling scale. Video clearly explains difference in electronegativity of metals and nonmetals and based on the difference in electronegativity polarity of the chemical bond is identified.

Electronegativity part 4- Polarity of bonds in organic molecules -
Video is explaining difference in electronegativity due to hybridization , due to formal charges and due to change in oxidation numbers of the central atom in the compound or molecules
Video is also very important for every competitive exam and it is more important for organic Chemistry and understanding of many concepts in organic chemistry.

Electronegativity part 5
video is basically explaining the meaning of the electrostatic potential maps, Induction ,dipole and how the difference in electronegativity in different compounds or molecules are responsible for chemical reactions for the mechanism in organic chemistry.
