Nitrogen trifluoride concentration at several latitudes since 2015. [22] NF3 measured by the Advanced Global Atmospheric Gases Experiment in the lower atmosphere (troposphere) at stations around the world. Abundances are given as pollution free monthly mean mole fractions in parts-per-trillion.
The N-O bond has 75% double bond character. This differs from the amine oxides where the amine is much more basic and with a positive charge. [ 5 ] The N-O bond-length is 1.158 Å; the N–F bond-length is 1.431 Å ; the bond angles ∠FNF is 101°; and the three bond angles ∠ONF = 117.
Against the expectations of VSEPR theory but consistent with Bent's rule, the bond angles of ammonia (NH 3) and nitrogen trifluoride (NF 3) are 107° and 102°, respectively. Unlike VSEPR theory , whose theoretical foundations now appear shaky, Bent's rule is still considered to be an important principle in modern treatments of bonding.
In thiazyl trifluoride N≡SF 3, the bond order between sulfur and nitrogen is 3, and between sulfur and fluorine is 1. In diatomic oxygen O=O the bond order is 2 (double bond). In ethylene H 2 C=CH 2 the bond order between the two carbon atoms is also 2. The bond order between carbon and oxygen in carbon dioxide O=C=O is also 2.
Consequently, the bond angles are set at 120°. For example, boron trifluoride. Angular: Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H 2 O), which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs.

The bond angle for water is 104.5°. Valence shell electron pair repulsion ( VSEPR ) theory ( / ˈ v ɛ s p ər , v ə ˈ s ɛ p ər / VESP -ər , [ 1 ] : 410 və- SEP -ər [ 2 ] ) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
