Assertion (A) H(2)O is the only hydride ...

Assertion (A) `H_(2)O` is the only hydride of group - 16 which is liquid at ordinary temperature.
Reason (R ) In ice , each oxygen atom is surrounded by two covalent bonds and two hydrogen bonding.

Text Solution

Verified by Experts

The correct Answer is:
B

Correct explanation. Due to extensive H-bonding , water exists as associated molecules . As a result, it has high b.p. and thus water is a liquid at room temperature.
