The correct order of increasing melting point is
- A \(\mathrm{Cr}<\mathrm{Ti}<\mathrm{V}<\mathrm{Mn}\)
- B \(\mathrm{V}<\mathrm{Ti}<\mathrm{Mn}<\mathrm{Cr}\)
- C \(\mathrm{Ti}<\mathrm{V}<\mathrm{Cr}<\mathrm{Mn}\)
- D \(\mathrm{Mn}<\mathrm{Ti}<\mathrm{V}<\mathrm{Cr}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Mn}<\mathrm{Ti}<\mathrm{V}<\mathrm{Cr}\)
Step-by-step Solution
Detailed explanation
The melting points of transition metals depend on the strength of metallic bonding, which is related to the number of unpaired electrons available for delocalization in the metallic lattice. The electronic configurations of the given elements are: \(\mathrm{Ti} (3d^{2} 4s^{2})\)…
