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 correct, and reason is the correct explanation of the assertion.

B

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

C

If assertion is correct, but reason is incorrect .

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
b
Correct explanation . `H_(2)O` is a liquid due to extensive hydrogen bonding and hence has high
boiling point.
