Question

Assertion : The value of enthaply of atomisation is maximum at about the middle of each series.
Reason : There is one uparied electron per d-orbital and this results in stronger interatomic interaction.
A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer 1

Correct Answer - A
Greater the number of valence electrons, stronger is the resultant bonding and higher the enthalpy of atomisation.
