    My chem teacher takes 55 minutes to explain this.

    why not show that there is an electron also coming from the P orbital?

    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?

    • @MSJChem
      @MSJChem  4 года назад +19

      Are you forgetting the 4 C-H bonds on the ring?

    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!

    • @MSJChem

      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).

    Can you explain why pi bonds don't exist without sigma bonds? Plus this vedio was very helpful thanks

    • @MSJChem
      @MSJChem  3 года назад +1

      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

    Shouldnt ethandioic acid have 5 sigma bonds and 2 pi bonds?

    • @MSJChem
      @MSJChem  3 года назад +1

      Are you forgetting the two O-H bonds which are one sigma bond each?

    where are the electrons in a pi bond??

    • @MSJChem

      In the pi orbitals
