Question

What is the "AXE" description of the tetrafluoroiodide (IF 4) anion? 480 € 0 x 5 ?

Answer 1

Ans. AX​​​​​4 E​​​​​​2

Explanation:

In 'AXE' description A represents central atom

X represents no of surrounding Atoms bonded to Central atom

E represents no of lone pairs present on the central Atom

Iodine has seven electrons in its valence shell and the given compound ( IF4-) has one negative charge means one electron from outside, so here iodine has total 8 valence electrons.

Out of 8 electrons of iodine, 4 are bonded with 4 Fluorines, and remaining four lie as 2 lone pairs around iodine.

Thus in tetrafluoroiodide anion ,

X = 4, E= 2

IF. No. of bonded atore to central atom= 4 No. of lone pains on I = 2 o Axy Ez oo L Election Geomet ny = Octahed sal Moleculeer georeto - Square planer
