Given below are two statements: One is labelled as Assertion AA and the other labelled as Reason R.R .
Assertion AA : Lithium halides are some what covalent in nature.

Reason RR : Lithium possess high polarisation capability.

In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. AAA is true but RR is false
  2. BAA is false but RR is true
  3. CBoth AA and RR are true but RR is NOT the correct explanation of AA
  4. DBoth AA and RR are true and RR is the correct explanation of AA

Correct answer

D. Both AA and RR are true and RR is the correct explanation of AA

Step-by-step solution

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