Hi sir, I am a little confused on count the sigma and pi bonds on the cyanobenzoic acid. Isn't there only 7 single bonds, 4 double bonds and 1 triple bond, making a total of 12 sigma bonds and 6 pi bonds?
So, in the Lateral/pi bond, how the internuclear axis will serve as a nodal plane? PS: This point was told by my teacher but I can't understand how, so can you pls explain. Thanks!
A nodal plane is an area where there is a 0% chance of finding an electron. A pi bond has a nodal plane that includes the internuclear axis (which is the space between the nuclei of two atoms bonded to each other). In other words, in a pi bond there is a 0% chance of finding an electron between the nuclei of the bonding atoms. The electron density in a pi bond is located above and below the nuclei of the bonding atoms (not between them).
The answer is complicated and requires an understanding of molecular orbital theory. This link has the explanation but be warned it is beyond the level of HL chemistry. chemistry.stackexchange.com/questions/32549/why-are-pi-bonds-only-formed-when-sigma-bonds-are-formed

No questions after watching this. Explained PERFECTLY. Subbed🙌🏾
Thank you my “phd teacher took one week to explain this” and I don’t get anything, but you WOW THANK YOU
Glad I could help.
My chem teacher takes 55 minutes to explain this.
MSJ Chem: *hold my alcohol group*
Glad I could help.
thank you so much for your videos, especially with the updated versions!
Glad I could help.
in 1:06
why not show that there is an electron also coming from the P orbital?

Are you forgetting the 4 C-H bonds on the ring?
Ohhh yes I get it now, thank you so much sir. Also I love your videos, they save my chemistry grades!
Glad I could help.
It's really helpful, Thank you so much 🌸
Thank you sir 🙏🙏🙏🙏🙏

@@MSJChem thank you sir!! You're a life saver
Sir is the bond between oxygen and hydrogen is counted ad a sigma bond
Yes.
Can you explain why pi bonds don't exist without sigma bonds? Plus this vedio was very helpful thanks

Shouldnt ethandioic acid have 5 sigma bonds and 2 pi bonds?
Are you forgetting the two O-H bonds which are one sigma bond each?
where are the electrons in a pi bond??
In the pi orbitals
Is it just me or the video keeps on loading and never starts?
Who's here from chem class?
