3. Give the molecular formula for each of the following compounds. You may want to copy each structure into your notebook first, convert it into a Lewis structure, before accounting for all the atoms in the molecule. List carbon and hydrogen first, and then all other atoms in alphabetical order. For example, CH3OH would be listed as CH4Oasmolecular formula. ( 8 pts.) a) 2 pts. b) 2 pts. c) 2 pts
