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.

A

If both assertion and reason are true, and reason is the correct explanation of the assertion.

B

If both assertion and reason are ture, but reason is not the correct explanantion of the assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
Correct exlplanation. Because of extensive H-bonding, `H_(2)O` has high b.p. and hence is a liquid at room temperature.
