Mark the correct statements about halogens.

Answer»

Electron AFFINITY of halogens is in the order `F gt Clgt Brgt I`.
HF is the STRONGEST hydrohalic acid.
`F_(2)` has lower bond dissociation energy than `Cl_(2)`
All halogens show VARIABLE OXIDATION states.

Solution :`F_(2)` has lower bond dissociation energy than `Cl_(2)` due to its SMALL size which results in interelectronic repulsion.
