CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313665 Assertion :
As lattice encrgy increases, melting and boiling points of ionic compound increases.
Reason :
As lattice energy increases, slability of ionic compound increases.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313666 Assertion :
Decrease in lattice enthalpy is not as sharp as increase in interionic distance.
Reason :
Change in interionic distance affects the structure, which compensates the otherwise change in lattice enhalpy.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
