11. Assertion : The Crystal structure gets stabilized even though the sum of elecron gain enthalpy and ionization enthalpy is positive . Reason : Energy is absorbed during the formation of crystal lattice.
a. If both assertion and reason are true and the reason is the correct explanation of the assertion
b. If both assertion and reason are true but reason is not the correct explanation of the assertion
c. If assertion is true but reason is false
d. If the assertion and reason both are false
e. if assertion is false but reason is true.
Ans. c
Explanation : Energy is released in the formation of the crystal lattice. It is qualitive measure of the stability of an ionic compound so assertion is true and reason is false.
