C357 PPS #3 Solutions Page 1 of 3 1) Rank the following compounds in order of decreasing acidity (1= strongest acid, 5= weakest acid). OH O Cl OH O Br OH O I OH O OH O F 1 5 4 3 2 2) Consider the molecular formula C 4 H 8 O. In the space below, draw and circle four distinct structural isomers that contain a total of four distinct functional groups (not counting alkanes!). More simply said, draw four distinct structural isomers for the molecular formula that, among all four of your structures, one would be able to find four distinct functional groups (not counting alkanes). Possible (there are others!!): O Ether OH Alcohol H OH H Alkene Alcohol O H Aldehyde O Ketone 3) Pi ( ) bonds are generally weaker than sigma (s) bonds. Offer a short explanation for this. A: p-orbitals of the bond overlap side-to-side, which is less effective than head-on overlap of orbitals in bonds. 4) Sodium lauryl sulfate (shown below), a detergent, is a common ingredient in shampoos and other cleaning solutions.

    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.
