NF3 kookpunt

The boiling point of NF3 is 129.06 0C/ 144.09 K/ -200.31 0F and the low value accounts for the low thermal stability.

NF3 toestand by kamertemperatuur

The state of NF3 at room temperature is gaseous. The low melting and boiling points accounts for the gaseous state of NF3.

NF3 Kovalente binding

NF3 is a molecule with covalent bonds. The electronegativity difference between N and F is 0.9 which is lower than 1.5 so it has covalent bonds being polar in nature as per Fajan’s rule.

NF3 kovalente radius

NF3 has covalent radius as the bond is formed between two non metals with electronegavity difference lower than 1.5. The covalent radius of each N-F bonds in NF3 is approximated at 140 pm.

NF3 elektronkonfigurasies

The electronic configuration of NF3 is represented by the electronic state of N and the connecting F atoms. Let us check in details below.

The electronic configuration of N in NF3 1s2 2s2 2p3 and the three fluorine atoms have 1s2 2s2 2p7. The three unpaired electrons in N forms three sigma bonds with three fluorine atoms. In doing so, the octet of N and F atoms are completed.

NF3 oksidasie toestand

The oxidation state or charge of NF3 is overall neutral but the cationic part and anionic part have different oxidation states. N due to being trivalence has +3 oxidation state and fluorine being most electronegative has a -1 charge.

NF3 alkaliese

NF3 is alkaline in nature due to the presence of 2 lone pairs of electrons in N that can show basic character to increase its alkalinity.

Is NF3 reukloos?

NF3 is not odorless as it has a faint smell accounting for the presence of nitrogen in the molecule.

Is NF3 paramagneties?

Paramagnetic are materials that shows paramagnetism owning to the presence of unpaired electrons in its domain. Let us understand in details below.

NF3 is not paramagnetic as the molecule has no unpaired electrons in its orbitals. The five valence electrons of N makes 3 sigma bonding with 3 fluorine atoms and the remaining two electrons of N stay as paired lone pair of electrons.

NF3 koolhidrate

NF3 form hydrates due to the presence of electronegative N and F atoms that can form intermolecular H-bonding as shown below with an example.

  • NF3 + 4 uur2O -> NF3. 4H2O

NF3 kristal struktuur

The crystal structure of NF3 in the alpha form is orthorhombic with lattice parameters a, b and c being not equal to one another and alpha = beta = gamma angles = 900.

NF3 polariteit en geleidingsvermoë

  • The polarity of NF3 is u = 0.24 D where D = Debye moment.
  • The low polarity value is due to the cancellation of dipole moment vectors of lone pair by 3 N-F bonds vectors.
  • The conductivity of NF3 is arm.
  • NF3 exact estimate value is however not studied broadly.

NF3 reaksie met suur

NF3 reacts with acid as it is a lewis base in the gaseous state and reacts with amphoteric molecule like H2O as shown below.

  • 2NF3 (G)  + 3H2O (g) -> 6HF (g) + NO (g) + NO2 (G)

NF3 reaksie met basis

NF3 generally do not react with bases as it already has alkaline nature which makes it unreactive towards bases.

NF3 reaksie met oksied

The reaction of NF3 with oxides generally metal oxides produces metal fluorides, N2 gas, O2 gas and few NOx gaseous particles where x = 1, 2. The general reaction is shown below.

  • NF3 + MgO -> N2 + OF2 + NOx

NF3 reaksie met metaal

The reaction of NF3 with metal are shown below with examples.

  • R-MgX + NF3 -> R-NF2 + R-R
  • R-Li + NF3 -> R-R + R-NF2
  • R-Cu + NF3 -> R-R
  • NF3 reacts with transition metals and alkali metals very selectively.

Gevolgtrekking

 NF3 is a trigonal pyramidal orthorhombic crystalline structure with unpleasant smell. It exists in the gaseous state with very low melting and boiling point.

Hallo. Ek doen my Meestersgraad in Chemie met 'n spesialisering in organiese en fisiese chemie. Ek het ook twee projekte in chemie gedoen - Een wat handel oor kolorimetriese skatting en bepaling van ione in oplossings. Ander in Solvatochromism bestudeer fluorofore en hul gebruike in die veld van chemie saam met hul stapeleienskappe op emissie. Ek het ook gespesialiseer in Resin chemikalieë.
