Chemistry - Complete d-block Question with Solution | TestHub

Melting point in transition elements depends on the strength of metallic bonding, which increases with the number of unpaired d-electrons.

Chromium (Cr) has very strong metallic bonding due to its $3d^{5}4s^1$ configuration, giving it the highest melting point among the given elements.

Vanadium (V) and Titanium (Ti) also have high melting points but lower than Cr.

Manganese (Mn) has an unusually low melting point because its half-filled $d^5$ configuration contributes less effectively to metallic bonding.

Copper (Cu) has a nearly filled d-subshell and the weakest metallic bonding among these, so it has the lowest melting point.

Therefore, the correct order is Cr > V > Ti > Mn > Cu, which corresponds to Option (C).
