One, or both, of the following structural formulas may be incorrect (i. e., they do not represent a real compound) because they have atoms with an incorrect number of bonds. Which of the labeled atoms have the incorrect number of bonds? Specify the incorrect atoms by letter in alphabetical order without spaces or commas., i.e. bd. If there are no incorrect atoms, write none. a) b) H H b d jele H H a H-N- H H-O DN с |d H O-H -H

Answer the following question with reference to the molecule below: 61 H3C H (a)  Label the shortest C–C single bond. (b)  Label the longest C–C single bond. (c)  Considering all the bonds, label the shortest C–C bond (d)  Label the strongest C–H bond. (e)  Account for the difference in bond lengths for C4–C5 and C5–C6, even though they are both C-C single bonds.

3. Circle the TWO true statements relative to the structure shown? (Assume enough lone pairs to satisfy octet rule for each atom; but there are some formal charges.) a. b. For lone pairs, O(1) would have two; N(2) one; and O(3) two For lone pairs, O(1) would have two; N(2) none; and O(3) three C. For lone pairs, O(1) would have one; N(2) one; and O(3) three d. For formal charges, O(1) would be neutral; N(2) cation; and O(3) anion e. For formal charges, O(1) would be neutral; N(2) neutral; and O(3) anion f. For formal charges, O(1) would be anion; N(2) cation; and O(3) neutral 1 HO 2 NH3
