Which of the following statement is not true
  • ✓
    Colourless compounds of transition elements are paramagnetic
  • B
    Coloured compounds of transition elements are paramagnetic
  • C
    Colourless compounds of transition elements are diamagnetic
  • D
    Transition elements form the complex compounds
✓

Answer

Correct option: A.
Colourless compounds of transition elements are paramagnetic
a
(a) Colourless compounds are those which have no unpaired electrons and paramagnetic substance do have unpaired electrons. Therefore paramagnetic substance possess colour.
