Question

Number of lone pairs of electrons on Xe atoms XeF2, XeF4 and XeF6 molecules are respectively

Answer 1

XeF2 have 3 lone pairs
XeF4 have 2 lone pairs
XeF6 have 1 lone pair..

Answer 2

Question:

In XeF2,XeF4 and XeF6, the number of lone pairs of Xe is???

Solution:

Xe has total of 8 valence electrons.

In XeF2,  2 electrons are shared thereby leaving three lone pair of electrons.

In XeF4,  4 electrons are shared thereby leaving two lone pair of electrons.

In XeF6,  6 electrons are shared thereby leaving one lone pair of electrons.

Hence, No of lone pair of electrons in XeF2, XeF4, XeF6 are 3,2,1 respectively.
