Protons
Neutrons
Electrons
Both (a) and (c)
In the following reaction,
P4 + 3NaOH + 3H2O → PH3 + 3NaH2PO2
phosphorus is oxidised
phosphorus is oxidised and reduced
phosphorus is reduced
sodium is oxidised
The passivity of iron in concentrated nitric acid is due to
ferric nitrate coating on the metal
ammonium nitrate coating on the metal
a thin oxide layer coating on the metal
a hydride coating on the metal
Phosgene is common name of
carbon dioxide and phosphene

The number of paired electrons in Xe atom of XeF2 is
3
5
4
2
A.
3
The dot structure of XeF2 is as follows:
Number of molecular hybrid orbitals = no. of sigma bonds + no. of lone pair of electrons.
No. of molecular hybrid orbitals = 2 + 3 = 5
Therefore, hybridisation is sp3d.
