JEE Main Chemistry question

Statement 1: Helium has lower entropy than gas, which has lower entropy than gaseous benzene. Statement 2: The larger the complexity of a molecule, the larger is its absolute entropy.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is NOT correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Entropy generally increases with structural complexity (more atoms, more rotational and vibrational modes), so (Statement 1) follows directly
