Answer: Paramagnetic (attracted to magnetic field).
- A Paramagnetic (attracted to magnetic field)
- B Diamagnetic and therefore weakly repelled by a magnetic field
- C Completely non-magnetic with zero interaction with a field
- D Antiferromagnetic with perfectly cancelling adjacent spins
Correct answer: A. Paramagnetic (attracted to magnetic field)
Explanation: Unpaired electrons generate magnetic dipoles; paramagnetic substances are attracted to external magnetic fields.
Aqueous solutions of transition metal ions show characteristic colours caused by electrons absorbing visible light to jump between split d-orbitals; the exact colour depends on the metal, its oxidation state, and surrounding ligands.
Concept context
Transition metals (d-block) and lanthanides/actinides (f-block). Known for coloured compounds, variable oxidation states, complex formation, and catalytic properties. Frequently tested in JEE and NEET.
