1. One lone pair - Seesaw shape 2. Two lone pairs - T-shape 3. Three lone pairs – linear The lone pairs occupy equatorial positions because they are 120 o from two bonding pairs and 90 o from the other two bonding pairs. Results in decreased repulsions compared to lone pair in axial position. Trigonal Bipyramidal electronic arrangement: AB 5 , AB 4 U, AB 3 U 2 , and AB 2 U 3 AB 4 U molecules have: 1.1. trigonal bipyramid electronic arrangement 1.2. seesaw shape 1.3. and are

    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.
