The cation \(\mathrm{N}_{2} \mathrm{F}^{+}\) is isoelectronic with \(\mathrm{N}_{2} \mathrm{O}\). a. What does it mean to be isoelectronic? b. Draw the Lewis structure of \(\mathrm{N}_{2} \mathrm{F}^{+}\). (Hint: The molecule contains a nitrogen-nitrogen bond.) c. Which atom has the +1 formal charge in the structure you drew in part (b)? d. Does \(\mathrm{N}_{2} \mathrm{F}^{+}\) have resonance forms? e. Could the middle atom in the \(\mathrm{N}_{2} \mathrm{F}^{+}\) ion be a fluorine atom? Explain your answer.

Draw the Lewis structure for dimethyl ether, \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\), given that the structure contains an oxygen atom bonded to two carbons: \(\mathrm{C}-\mathrm{O}-\mathrm{C}.\)
