Correct order of boling point of d-block series of corresponding elements is
Open in App
Solution
The correct option is B 3d < 4d < 5d
Boiling point of transition elements increases down the group.
Thus, 3d series elements has lesser boiling points than 4d series and 4d has lesser boiling points than 5d series elements. This is due to the occurrence of more frequent metal–metal bonding in compounds of the heavy transition metals.
Thus, the correct answer is option (b).
