QJEEM07Ch4b7a: JEE Main 2007 Chemistry - Class 12 JEEM07Ch4b7a Solution: The actinoids exhibits more number of oxidation states in…

The actinoids exhibits more number of oxidation states in general than the lanthanoids. This is because :

Multiple Choice Options

  • A the 5f orbitals are more buried than the 4f orbitals
  • B there is a similarity between 4f and 5f orbitals in their angular part of the wave function
  • C the actinoids are more reactive than the lanthanoids
  • D the 5f orbitals extend further from the nucleus than the 4f orbitals

Step-by-Step Verified Solution

NOTE : More the distance between nucleus and outer orbitals, lesser will be force of attraction on them. Distance between nucleus and 5f orbitals is more as compared to distance between 4f orbital and nucleus. So actinoids exhibit more number of oxidation states in general than the lanthanoids.
