Refer to the Integrative Example. A compound related to nitryl fluoride is nitrosyl fluoride, FNO. For this molecule, indicate 

(a) A plausible Lewis structure and 

(b) The geometric shape. 

(c) Explain why the measured resultant dipole moment for FNO is larger than the value for FNO₂.

Integrative Example

Nitryl fluoride is a reactive gas useful in rocket propellants. Its mass percent composition is 21.55% N, 49.23% O, and 29.23% F. Its density is 2.7 g/L at 20 °C and 1.00 atm pressure. Describe the nitryl fluoride molecule as completely as possible—that is, its formula, Lewis structure, molecular shape, and polarity.
