Question

Assertion (A): The boiling point of H2O (373 K) is much higher than that of HF (293 K). Reason (R): A water molecule can form up to four hydrogen bonds (two as donor, two as acceptor), whereas an HF molecule can form only about two.

Accepted Answer

Both A and R are true and R is the correct explanation of A

Answer

Both A and R are true but R is not the correct explanation of A

Answer

A is true but R is false

Answer

A is false but R is true

Assertion (A): The boiling point of $H X_{2} O$ ( $373 K$ ) is much higher than that of $HF$ ( $293 K$ ). Reason (R): A water molecule can form up to four hydrogen bonds (two as donor, two as acceptor), whereas an $HF$ molecule can form only about two.
