Throughout this quiz, some to lone pairs of electrons may be "missing" from skeletal structures. it may help to fill them in. 1. Predict and label the conjugate acid/base pairs of the following acid-base reaction assuming it reacts as follows: - Would the reaction above favor the products or reactants? (hint: pKa's might help). Explain. - Based on your answer, would this be a good way to deprotonate acetylene, HCCH? 2. Determine which of the following would effectively deprotonate an acid with a pK4 of 30 . (hint: pk's might help) Br: 3. Determine which species will act an acid and act as a base in a product favored reaction. Predict. and label conjugate acid/base pairs. Use curvy arrow notation to show the movement of electrons during the reaction. 4. In each molecule below, circle on labeled proton which would be more/most acidic. 5. For each pair of bases below, circle the stronger base: HSe : HO
