Assertion (A): Lithium chloride is predominantly covalent compound.
Reason (R ): electronegativity difference between Li and CI is small.

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 assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
c
`LiCl` is predominantly covalent because small cation `(Li^(+))` causes more polarization of `Cl^(-)` to develop covalent nature.
