For extra practice, please read the book and do the following problems in: Chapter 1 #1-26, 37, 38, 39, 40, 43, 44, 45, 47, 48, 49, 51, 54, 56. 1. Each of the following structures contains at least one error structural error. Identify the error(s) and then draw a similar correct structure. NOTE: There are many possible answers to each one of these! You may add an atom, subtract an atom, and rearrange the atoms, etc. in order to come up with a correct structure. All structures should be neutral (uncharged) and formal charge for each atom should be 0. Follow the rules of valence! Structure Error in the structure Corrected Structure H more O-I H2N H als NH N 2. Structures! In the boxes below, draw a valid structure include all lone pairs and formal charges if appropriate) for the indicated molecular formulas and functional group conditions. a. C,H,O, that contains an ester. b. CH.O that contains and aldehyde c. CHO that contains an ether. d.C.H.ON that contains an amide c.CH.Od that contains a carboxylic acid and two ketones. 2 Page
