Question

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: 

(1) A is true but R is false 

(2) A is false but R is true 

(3) Both A and R are true but R is NOT the correct explanation of A 

(4) Both A and R are true and R is the correct explanation of A

Answer 1

(4) Both A and R are true and R is the correct explanation of A

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