order of overlap of atomic orbitals from highest extent of overlap t.pdf

order of overlap of atomic orbitals from highest extent of overlap to lowest is,
I2 > IBr > ICl > IF
Because,
I2-is homo diatomic molecule and having good overlapping between the atomic orbitals of two
iodine atoms.
IBr-is a hetero di-atomic molecule and having almost good overlapping between the atomic
orbitals of iodine and bromine atoms even though these two atoms belongs to different periods.
ICl-is a hetero di-atomic molecule and having moderate overlapping between the atomic orbitals
of iodine and chlorine atoms.Because, these two atoms belongs to different periods and size
different is more.
IF-is a hetero di-atomic molecule and having poor overlapping between the atomic orbitals of
iodine and fluorine atoms.Because, these two atoms belongs to different periods and size
different is too more.
