Interhalogen compounds : Halogens react with each other to form a number of compounds called interhalogen compounds, whose general formula is
where = less electronegative atom (have larger size)
= more electronegative atom (have smaller size)
n =no. of more electronegative atoms
They are of four types :
= ClF, BrF, IF, BrCl, ICl, IBr
Naming : The halogen with positive oxidation state named first and with negative oxidation state named after first with suffix 'ide'.
Example : Bromine trichloride
Preparation of Interhalogen Compounds :
By direct combination :
