Question

Statement I: $LiCl$ is predominantly a covalent compound.
Statement II: Electronegativity difference between $Li$ and $Cl$ is too small.
Choose the correct option regarding Statement I and Statement II from the following:

• A. Statement I is true; Statement II is true; Statement II is the correct explanation of Statement I
• B. Statement I is true; Statement II is true; Statement II is not the correct explanation of Statement I
• C. Statement I is correct; Statement II is incorrect
• D. Statement I is incorrect; Statement II is correct

Answer 1

The correct option is C Statement I is correct; Statement II is incorrect

Statement I is correct but Statement II is incorrect. The covalency in $LiCl$ is due to small size of $L{i}^{+}$ ion which brings about large amount of polarisation in bond.
