BOND POLARITY, QUESTION, HAPE OF XENON TETRAFLOURIDE XeF4:
SHAPE OF XENON TETRAFLOURIDE XeF4:
Ground state configuration of xenon is;
56Xe = 2, 8, 18, 18, 8
=152, 252, 2p6, 352, 306, 3d10, 452, 4p6, 4d10, 4f0, 552, 5p6.
On orbital hybridization two electrons from 5 pare promoted to empty 4f orbital. Excited state configuration of Xenon is;
There are two lone pair and four bond pairs around the central
xenon atom. The shape of XeF4 is square planer. Two lone pair occupy
axial position and four bond pair angles are 900.
= 152, 252, 2p6,
352, 3p6, 3d10, 452, 4p6,
4d10, 4f0, 5s2, 5p3.
Separation
of +ve and –ve charge within a compound is called bond polarity and such
compounds are called polar compounds. Due to this bond polarity some covalent
compounds show ionic behavior e.g; hydrogen chloride gas readily dissolves in
water to produce ionic solution. Similarly some ionic compounds due to extreme
bond polarity shows typical covalent properties. e.g; Aluminum chloride is
soluble in benzene (organic solvent) as well as it is subline solid i.e; having
no crystal lattice.
