Exceptions To The Octet Rule - Lewis Dot Diagrams

This chemistry video tutorial discusses the exceptions to the octet rule while providing the lewis dot diagrams of the molecular compounds involved. BH3 has an incomplete octet - that is, it has less than 8 electrons. Molecules such as ICl5 and PCl5 have an expanded octet which means the center atom has more than 8 electrons. The last category are molecules with odd number of electrons such as NO and NO2. These will always be electron deficient and contain an incomplete octet at the nitrogen atom.

I can't begin to explain the happiness I feel when I type a subject in the search bar and I see that black background with neon numbers and letters pop up. Thanks so much!

[hadeerrashad]

you are the ONLY one who explains the concepts in such an excellent way!!!! Please keep making more videos.

Dude, from one teacher to another. You're great at this. (Even if I am 6 years late to the party.)

Your accent make's it interesting. "So that's BH3, that's just how it is. You gotta problem wit dat, wise guy?" OH, LOOKAT dis guy, with his exception to the octet rule. "HEY, I'm doin' Chemistry heah." etc. etc.

Just to help you guys-
when he draws ICl5, he forgets to draw the 6 valence electrons around EACH Cl.
Remember, the valence electrons are still there!

no body is perfect..but you are perfect.

Professor Organic Chemistry Tutor, thank you for a fantastic analysis into the Exceptions to the Octet Rule in AP/General Chemistry.The examples/practice problems shows the complete Octet Rule and when they are violated in Modern Chemistry. Professor Organic Chemistry Tutor, thanks to the viewers for finding and correcting the errors in this video.

Dude you are literally the best teacher out there man

[blurr_]

you deserve a nobel prize for saving the next generation of stem majors

[blackraven]

Thank you! Unlike most people who come to youtube to learn, I have had a phenomenal professor, however even then I was unable to grasp VSEPR and Lewis Structures. you have made it so incredibly clear.

[John-bqlp]

man i love coming to your videos after I learn this stuff in school. It really helps to embed the information. ur a legend man.

[gartyqam]

2:02 sounds like "the reason why nitrogen can have 8" -- he meant to say nitrogen CAN'T have more than 8. just a clarification for u guys

[ashudesmond]

You're just too much dude.
Thanks. Your videos have really helped me. Wish I knew you much earlier, I would have scored a better grade in math and chemistry.

But am doing well in the university now. Thanks to your videos.

[anoushkaghosh]

I struggled with this concept for days. Thankyou so much☺️☺️.

[flwrtyong]

thank you so much, I’ve been struggling for weeks, and I finally understand!!

[Matt-qtep]

Thank you for this help I appreciate it! But there should be 3 lone pairs on each Cl atom at 5:45

[shahin]

Thank you again from the bottom of my heart!!! btw, you should do a face reveal video! :)

[victormai]

better than some of the videos with many more views

[imerickclark]

i just want to say that I have my chemistry final tmrw and you have been a HUGE help you have no idea! Without you, I would have failed most of my chemistry exams! THANKS

[serenacrawford]

You are a God sent! Whenever I need help I know i'll find the answer in your videos and you always have clever ways to figure out problems! Thank you

[regiice]

Your videos gave me success in chemistry
