Explanation
HF is liq. Because of int . molec. H - Bond
I – 131 is used for treatment of thyroid disorders.
As electronegativity decreases reactivity also decreases
Br. Is a liquid at room temp.
AgI is covalent compound.
Due to unpaired e– - ClO2 is paramagnetic.
CrO2Cl2 is a orange red gas
Acc to Fajan's rule , largest cation & smallest an ion
AgCl is water insoluble chloride.
Small atomic size of Li & F, lattice energy highest
Fact.
Cl2O6 is formed by reaction of ClO2 & O3.
due to H - bonding free ions are not present in aq sol. Hence bad condc.
