Question

Interhalogen compounds are covalent due to___________.

Answer 1

Interhalogen compounds:

• Interhalogen compounds are compounds formed when halogen group elements react with each other.
• These compounds are formed due to the direct combination or by the action of a group of 17 elements with a lower interhalogen compound.
• The small difference in the electronegativities of interhalogen compounds polarises the bond and thus makes the bond covalent in nature.
• The polarity and weak bonding of interhalogens make them more reactive than halogens.
• Examples are Chlorine monofluoride $\mathrm{ClF}$, Bromine trifluoride ${\mathrm{BrF}}_3$ etc.

Hence, interhalogen compounds are covalent due to the low electronegativity difference between halogens.
