Question

Krypton difluoride can be produced by arching large amounts of energy through a 1:1 mixture of Kr and F and elevated pressures. It can be stored at -78 ^oC, but decomposes upon heating to room temperature. Try to rationalize this by drawing an MO diagram for this linear molecule. A full MO diagram will answer this question, but an MO giagram that involves the p_z orbitals on each of the atoms is sufficient to describe the bonding All the other p orbitals are nonbonding on both Kr and F. The three s orbitals bonbine to make filled bonding, nonbonding and antibonding molecular orbitals. According to the MO diagram, the bond order for each Kr-F bond in KrF₂ is ___.
