Which of the following interhalogen compounds does not exist:a)ClF3b)F...
Explanation:
Interhalogen compounds are formed between two different halogens. These are of different types such as IF, BrF, ClF, BrCl, etc. They can be easily prepared by the direct combination of halogens under appropriate conditions. Some examples of interhalogen compounds are:
a) ClF3
b) FCl3
c) IF5
d) BrF3
Out of these, FCl3 is the only compound that does not exist. This can be explained as follows:
Reasons for non-existence of FCl3:
1. Violation of the Octet Rule: FCl3 violates the octet rule as the central atom (Cl) has only 6 electrons in its valence shell.
2. High Electron Density: Fluorine is a highly electronegative element, so it attracts electrons towards itself. Due to this, the electron density around the central atom (Cl) becomes very high. As a result, it is difficult to add more electrons to the central atom.
3. Lack of Empty d-orbitals: Chlorine does not have any empty d-orbitals, which are required to accommodate the lone pairs of electrons from the fluorine atoms. Therefore, FCl3 cannot be formed.
Conclusion:
FCl3 does not exist due to the violation of the octet rule, high electron density, and lack of empty d-orbitals.

In case of interhalogen compounds 2nd element should be more electronegative than 1st element.
