The ortho and meta isomers would have non-zero dipole moments. Each chlorine pulls electron density towards itself from the carbon to which it is attached. In the para isomer, the chlorines are pulling the electron density in exactly opposite directions so the bond dipoles exactly offset. In the other 2 isomers, the dipoles are partly in the same direction and add. 40. a) b) c) 47. a) sp 2 b) sp 3 c) sp d) sp 3 d e) sp 3 d 2 48. a) sp 3 b) sp c) sp 2 d) sp 3 d e) sp 3 d 2 56. a) 120º, 120º, 109.5º b) sp 2 , sp 2 , sp 3 c) 21 58. All three possible Lewis structures are shown below. The hybridization on sulfur is sp 2 . S O: O .. .. .. .. :O: : S O: O .. .. .. .. :O: : S O: O .. .. .. .. :O: : Yes, SO 3 will exhibit delocalized bonding. The sulfur bonds to each oxygen with a bond via overlap of the sp 2 hybrid with an oxygen p orbital. In each resonance form the sulfur p orbital overlaps with a p orbital on a different oxygen.

    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.
