Final answer:
The compound 'Formaldehydetetramethylamidofluoride' is correctly named by considering its formaldehyde component, the tetramethyl group attached to nitrogen, and the fluoride compound, resulting in option 4 being the correct answer.
Step-by-step explanation:
The correct name for the compound is 'Formaldehydetetramethylamidofluoride'. When naming compounds, we look at the components and how they combine. Formaldehyde is the common name of methanal, indicating a carbonyl group attached to the end of a carbon chain. In nitrogen compounds with alkyl (methyl) groups, we use the prefixes 'methyl-', 'dimethyl-', 'trimethyl-' and 'tetramethyl-' depending on the number of methyl groups attached. In our case, 'tetramethyl-' indicates four methyl groups are present. Furthermore, compounds containing the fluoride ion typically end in '-fluoride'. Therefore, combining these naming rules, we obtain 'Formaldehydetetramethylamidofluoride' as the proper name of the compound, making option 4 the correct answer.
