Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : LiCl is predominantly a covalent compound.

Reason (R) : Electronegativity difference between Li and Cl is too small.

In the light of the above statements, choose the correct answer from the options given below

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

If assertion is true but reason is false

Answer 2

$LiCl$ is covalent due to high polarising power of $Li ^{+}$. According to Fajan 's rule, the smaller the size of cation and the larger the size of anion, greater is the polarising power and hence greater is the covalent character.
