For the molecular formula C_3H_4NOCl, give a Lewis structure for the following indicated structural isomers. Although you may use full Lewis structures, condensed structures such as "bond-line" (zigzag) are fine. There are many correct answers. (How many rings + double bonds does this formula require? It looks like it must be at least two. Perhaps show a calculation.) a. two double bonds b. one ring and one double bond c. a nitrile functional group d. an amide functional group

Based on the Lewis structure, all of the following statements are true of disodium fumarate. Explain whether or not the statement is also true based on the electron density plot. Clearly indicate which feature and which electron density plot best supports your reasoning. a) This molecule has both ionic and covalent bonds. b) There is an extra electron on two of the oxygen atoms (one on each side of the molecule) resulting in a -1 charge. c) There are two...
