Chapter 7 and 8 worksheet 1. Dehydration reactions: Provide the organic products formed in the following reactions. For reactions that form more than one product, indicate which product, if any is formed in greater amounts. The following problems are a supplement, n o t a r e p l a c e m e n t t o the assigned problems in Chapter 7 and 8. C OH H 3 C CH 3 CH 2 CH 3 H 2 SO 4 (a) (b) OH H 2 SO 4 (c) OH H 2 SO 4 2. Mechanisms: Being careful to balance each step with mass and charge, and using curved arrows to show the flow of electrons, provide a step-by-step mechanism that accounts for the following reactions. Label each step with the appropriate mechanistic step notation. Also see 7.40 and 8.37. (a) (b) (c) CH 3 CHCHCH 3 CH 3 OH H 2 SO 4 C C H 3 C H 3 C H CH 3 after completeing this mechanism, review your answer for 1(c)
