QJEEM19Ch6c62: JEE Main 2019 Chemistry - Class 12 JEEM19Ch6c62 Solution: The maximum number of possible oxidation states of actinoides…

The maximum number of possible oxidation states of actinoides are shown by :

Multiple Choice Options

  • A nobelium (No) and lawrencium (Lr)
  • B actinium (Ac) and thorium (Th)
  • C neptunium (Np) and plutonium (Pu)
  • D berkelium (Bk) and californium (Cf)

Step-by-Step Verified Solution

Actinoid 'Th' shows oxidation state = +4

Actinoid 'Ac' shows oxidation state = +3

Actinoid 'Pu' shows oxidation states = +3, +4, +5, +6, +7

Actinoid 'Np' shows oxidation states = +3, +4, +5, +6, +7

Actinoid 'Bk' shows oxidation states = +3, +4

Actinoid 'Cm' shows oxidation states = +3, +4

Actinoid 'Lr' shows oxidation states = +3

∴\therefore Maximum oxidation state is shown by Np and Pu.
