7. The F-F bond is weak because : (1) The repulsion between the nonbonding pairs of electrons of two fluorine atoms is large(2) The ionization energy of the fluorine atom is very low(3) The length of the F-F bond much larger than the bond lengths in other halogen molecules() The F-F bond distance is small and hence the internuclear repulsion between the two F atoms is venylow

Answer» (1)EXPLANATION: Flourine has a very SMALL size and SHORT bond length . Therefore, due to SIGNIFICANT repulsion between lone pairs , the bond BECOMES weak.
