Question

(A) More is the value of van der Waals' constant 'a', greater is the tendency of liquefaction.
(R) 'a' measures the magnitude of 'force of attraction among the molecules.

• A. Both (R) and (A) are true and reason is the. correct explanation of assertion
• B. Both (R) and (A) are true but reason is not correct explanation of assertion
• C. Assertion (A) is true but reason (R) is false
• D. Assertion (A) and reason (R) both are false
• E. Assertion (A) is false but reason (R) is true

Answer 1

The correct option is A Both (R) and (A) are true and reason is the. correct explanation of assertion

More is the value of van der Waals' constant 'a', greater is the tendency of liquefaction.

'a' measures the magnitude of 'force of attraction among the molecules.

So both (R) and (A) are true and reason is the. correct explanation of assertion.

Hence option A is correct.
