You don’t have to “prove” the bonding b d i th bit l b lik I h by drawing the orbital boxes like I have • I did this to show you what is happening at I did this to show you what is happening at the molecular level • All you have to do is: All you have to do is: – draw the Lewis structure t th l t d i b t t – count the electron domains about an atom – predict hybridization from number of domains – single bonds are sigma bonds – double and triple bonds are pi bonds S.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
