10. Lewis Structures

MIT 5.111 Principles of Chemical Science, Fall 2014
Instructor: Catherine Drennan

Lewis structures are simplistic views of molecular structure. They are based on the idea that the key to covalent bonding is electron sharing and having each atom achieve a noble gas electron configuration. Lewis structures correctly predict electron configurations around atoms in molecules about 90% of the time. They are not perfect, but writing a Lewis structure is a lot easier than solving the Schrödinger equation, so we recommend that you watch this lecture.

I wish you were my professor. I’ve taken chemistry three times now. I can not grasp it and the professors speak to me like I’m dumb because I’m dyslexic. You taught me more in 48 min then three semesters

I am Anu from India and I am so happy by all the professors of MIT. They teach do good and I can't express my happiness by the text.😃😃😘😘😃

I'm enjoying this lecturer, so excited.

[khanyahya]

thank you so much I really love your lectures. am really grateful

Best educator for chemical science
.. Enjoyed it so much

The problem with the CSN structure can be easily solved if we base the central atom on the basis of lowest group number or EN instead of lowest ionisation energy.

I have left only 7 month to prepare for neet exam because i caught in depression in last of 6 month due to waking up late night for one month now i pass my 12th exam in july when vikram pragyan 3 was landed successfully on south pole of the moon.i was failed in physics 2 time one time in board exam and one time in compartment exam but on 3rd attempt i got pass in physics and score highest marks in physics thanks to the mit professors who help me lot 😊😊 ❤❤to clear my conceptual topics.

10:34, does anybody knows where the 2, 8 and 8 comes from? I don't understand, I thought we were supposed to get to 8 valance electrons to complete, shouldn't it be 4 for C and 3 for N??

As always...I love this video! Thanks so much for posting. Sadly...I did NOT have this instructor/teacher in high school.. so now...way later...I get the "joke" :)

[MuhammadUsman-opus]

India have NCERT book and America have which type of book? Can anyone tell me

[shanthikishorekumar]

Thank you very much! You are awesome! and excellent, superb, world class teacher.
Thanks for helping me.
I can not find your video "INTERMOLECULAR FORCES" please help me Thank you so much:)

[VikashChaurasiya-wd]

PW vs Mit who will win ?😅 I think Mit will win

[mukeshsolanki]

Hey MIT... I m from In which this is taught... May I know please?
