Assertion : Melting and boiling points of `D_2O` are higher than those of ordinary `H_2O`.
Reason : `D_2O` has lesser degree of association and lower molecular mass than `H_2O`.

A

Statement 1 is True, statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
C
`D_(2)`O has higher molecular mass and greater degree of association than `H_(2)`,O and thus, has higher melting and boiling points. Linked Comprehension Type
