Interhalogen compound which exists in dimeric form is:
1 \(\mathrm{ICl}_{3}\)
2 \(\mathrm{BrF}_{5}\)
3 \(\mathrm{ICl}\)
4 \({\rm{I}}{{\rm{F}}_{\rm{7}}}\)
Explanation:
\(\mathrm{ICl}_{3}\) exist in dimeric form \(\mathrm{I}_{2} \mathrm{Cl}_{6}\)
CHXI11:THE P-BLOCK ELEMENTS

Give reason to explain why \(\mathrm{ClF}_{3}\) exists but \(\mathrm{FCl}_{3}\) does not exist.
1 Flourine is more electronegative
2 Flourine has more electron gain enthlapy
3 Chlorine has less electron gain enthalpy
4 Chlorine is more reactive
Explanation:
Because fluorine is more electronegative as compared to chlorine.
