IF7 exist but Brf7 does not exist. why?
Answers
Answer:
If
7
exist but Brf_{7}Brf
7
does not exist because 7 small fluorine atoms can easily accommodate around large iodine atom.
Explanation:
It is known that fluorine, bromine and iodine are all group 7 elements. The size of these elements increases on moving down the group. Hence, fluorine is the smallest in size and iodine is largest in size.
So, IF_{7}IF
7
is an AX_{7}AX
7
type of interhalogen compound that is formed when there is large electronegativity difference between two halogens and also there is large difference between sizes of the halogen atoms.
Seven small fluorine atoms are able to accommodate around a large iodine atom but seven fluorine atoms are not able to accommodate around a bromine atom due to electronic repulsion between the fluorine atoms.
