NF3 تكوينات الإلكترون

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 حالة الأكسدة

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 قلوي

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.

هل NF3 عديم الرائحة؟

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

هل NF3 مغناطيسي؟

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 هيدرات

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 + 4H+2O -> NF3. 4H2O

NF3 هيكل الكريستال

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 القطبية والتوصيل

  • 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 انه فقير.
  • NF3 exact estimate value is however not studied broadly.

NF3 تفاعل مع الحمض

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 (ز)  + 3H2O (g) -> 6HF (g) + NO (g) + NO2 (ز)

NF3 رد فعل مع القاعدة

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