Given below are two statements: One is labelled as Assertion A and the other labelled as Reason R . Assertion A : Lithium halides are some what covalent in nature. Reason R : Lithium possess high polarisation capability. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. AA is true but R is false
  2. BA is false but R is true
  3. CBoth A and R are true but R is NOT the correct explanation of A
  4. DBoth A and R are true and R is the correct explanation of A

Correct answer

D. Both A and R are true and R is the correct explanation of A

Step-by-step solution

Lithium due to small size has very high polarization capability and thus increases covalent nature in Halides.
