## 261 Week 5 Quiz (Covering week 4, Lecture Days 6 and 7) 1. Rank the indicated protons in each of the following in terms of most acidic to least acidic (most acidic = 1, least acidic = 3). (12 pts) There are three main CARIO effects involved in this example. List them in order of importance. - Atom - Resonance - Induction There are two main CARIO effects involved in this example. List them in order of importance. - Charge - Orbital 2. a. Rank these from strongest to weakest acid (4 pts) b. Thoroughly explain your rankings (4 pts) - OH vs. NH - atom effect, O more electronegative - OH vs. ROH - resonance effect, O spread out 3. For each of the following Bronsted-Lowry acid-base reactions: a. Predict the products and draw the mechanism (4 pts) b. Identify the acid on each side and label the stronger acid and weaker acid (6 pts) c. Write an arrow to show the direction favored by equilibrium (1 pt) 4. Draw the structure of 4,4-dimethyl-3-octanol (4 pts) 5. Name this molecule using IUPAC rules (5 pts) - 4-ethyl-2-methylhexane The image depicts a chemical quiz with five questions. It includes structures of molecules and reactions. The first question involves ranking the acidity of protons based on various factors including atom effect, resonance effect and induction. Questions 2 and 3 involve acid-base reactions and the explanation of various effects involved in the process. The last two questions are focused on drawing and naming organic molecules. The answers provided are hand-written on the image and include additional information about each step.
