Chapter 11, Problem 52IAE

Fluorine nitrate, ${\text{FONO}}_{\text{2}}$ , is an oxidizing agent used as a rocket propellant. A reference source lists the following data for ${\text{FO}}_{\text{2}}{\text{NO}}_{\text{2}}$ . (The subscript “a” shows that this O atom is different from the other two.)

Bond lengths: N−O = 129 pm;

${\text{N–O}}_2$ = 139 pm; ${\text{O}}_2–\text{F}$ =142 pm

Bond angles: O−N−O = 1250°;

${\text{F–O}}_2\text{–N}=150°$ ${\text{NO}}_{\text{2}}\text{F}$ plane is perpendicular to the ${\text{O}}_{\text{2}}{\text{NO}}_{\text{2}}$ plane

Use these data to construct a Lewis structure(s), a three-dimensional sketch of the molecule, and a plausible bonding scheme showing hybridization and orbital overlaps.
